ROOFING SYSTEMS UTILIZING A PRIMER INCLUDING A SILICON- TERMINATED POLYMER [0001] This application claims the benefit of U.S. Provisional Application Serial No. 63/137,795 filed on January 15, 2021, which is incorporated herein by reference. FIELD OF THE INVENTION [0002] Embodiments of the invention are directed toward roofing systems that include lap seams formed by using a primer that includes a silicon-terminated polymer. BACKGROUND OF THE INVENTION [0003] Large, flexible polymeric sheets, which are often referred to as membranes or panels, are used in the construction industry to cover flat or low-sloped roofs. These membranes provide protection to the roof from the environment, particularly in the form of a waterproof barrier. As is known in the art, commercially popular membranes include thermoset membranes such as those including cured EPDM (i.e., ethylene-propylene-diene terpolymer rubber) or thermoplastics such as TPO (i.e., thermoplastic olefins). [0004] These membranes are typically delivered to a construction site in a bundled roll, transferred to the roof, and then unrolled and positioned. The sheets are then affixed to the building structure by employing varying techniques such as mechanical fastening, ballasting, and/or adhesively adhering the membrane to the roof. The roof substrate to which the membrane is secured may be one of a variety of materials depending on the installation site and structural concerns. For example, the surface may be a concrete, metal, or a wood deck, it may include insulation or recover board, and/or it may include an existing membrane. [0005] In addition to securing the membrane to the roof, the individual membrane panels, together with flashing and other accessories, are positioned and adjoined together so as to achieve a waterproof barrier on the roof. Typically, the edges of adjoining panels are overlapped, and these overlapping portions are adjoined (i.e. seamed) to one another through a number of methods depending upon the membrane materials and exterior conditions. One approach involves providing adhesives or adhesive tapes between the overlapping portions, thereby creating a water resistant seal. [0006] Before preparing EPDM roofing seams, it is necessary that any talc or mica anti-stick agents be removed from the membrane surface prior to applying the adhesive system to be used to join adjacent membrane sheets together. If the removal process is not thorough, the particles of talc or mica prevent the adhesive material employed from thoroughly coating the surface area covered by the anti-stick agent. This then results in inferior adhesion, subsequent decoupling of the joint, and eventual penetration of water through the seam. [0007] Therefore, it is desirable to use a primer on the EPDM membrane substrate before applying the neoprene or butyl based adhesives. These primers generally include a dilute solution of rubber and resins in a suitable solvent. The primer is applied to the surfaces to be joined prior to application of the membrane adhesive in order to improve the final seam adhesion. The application of the primer and the evaporation of the solvent occur before the application of the splice adhesive. The strength and durability of the final bond between adhesive and substrate depend greatly on the strength of the bond created by the primer. Certain conventional commercial primers provide relatively poor bond strengths when used with neoprene or butyl based adhesives.

[0014] Fig. 2 is a perspective elevational view of a pre-primed roofing membrane panel according to embodiments of the invention. [0015] Fig. 3 is a cross-sectional side view of a roofing membrane composite according to embodiments of the present invention. DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS [0016] Embodiments of the invention are based, at least in part, on the discovery of a method for forming roofing membrane systems by utilizing a lap-edge primer that includes a silicon-terminated polymer. The lap-edge primer has unexpectedly been found to exhibit desirable properties including the ability to form advantageous seams when utilized in conjunction with conventional adhesives, such as splice tape. The use of the primer compositions of this invention provides several advantages including the formation of strong lap seals, and the ability to apply the primer composition, especially in the field, with reduced VOC release to the environment. The primer composition has also proven to be versatile. For example, in some embodiments, the primer composition can be applied in the field, and then an adhesive is subsequently field applied to form the seam. Alternatively, the primer composition can be pre-applied prior to delivery to location of installation (e.g. in a fabrication facility). A release film can be applied to the primed area, or the primed area can remain exposed during storage, shipping and handling without deleterious impact to subsequent formation of a seam. In still other embodiments, following pre-application of the primer composition (e.g. at a fabrication facility), an adhesive, such as a pressure-sensitive adhesive tape, can likewise be pre-applied to the primed area to form a composite membrane. PRIMER COMPOSITION [0017] As suggested above, the methods of the present invention employ a lap-edge primer composition that includes a silicon-terminated polymer. In one or more embodiments, the lap-edge primer compositions, which may also be referred to as uncured primer compositions or simply primer composition, include a polymer having silicon- containing hydrolyzable terminal group and optionally one or more of a plasticizer, a moisture scavenger, an adhesion promoter, and a catalyst. Other optional ingredients may include an antioxidant, a stabilizer, a tackifier, filler, a crosslink inhibitor (a.k.a. retarder), a plasticizer, a thixotropic compound, and/or an anti-degradant. SILANE-TERMINATED POLYMERS [0018] In one or more embodiments, the polymer having a silicon-containing hydrolyzable terminal group may be referred to as a silane-terminated polymer or a silyl- terminated polymer. The term “silicon-containing hydrolyzable terminal group” refers to a group wherein at least one silicon atom is associated with a hydrolyzable group, such as a hydrocarbyloxy group (e.g. methoxy or ethoxy group), and is subject to hydrolysis and polymerization through interaction with water (i.e., moisture). In one or more embodiments, the polymer is telechelic, which refers to the fact that the polymer is linear and include a silicon-containing hydrolyzable terminal group at each end of the polymer chain. In one or more embodiments, the silyl terminal end includes at least two, and in other embodiments at least three hydrolyzable groups (e.g. the hydrolyzable group is a trimethoxy or triethoxy silyl group). [0019] In one or more embodiments, the backbone of the silyl-terminated polymer includes one or more silicon-containing repeat units (e.g. a polysiloxy backbone). In other embodiments, the backbone of the silyl-terminated polymer is devoid of silicon-containing internal repeat units (e.g. a non-siloxy backbone). In one or more embodiments, the backbone of the silyl-terminated polymer includes a polyether, polyester, polyurethane (SPUR), or the like.

These moisture scavengers are available under the tradename Y-15866 (Momentive). ADHESION PROMOTER [0043] In one or more embodiments, an adhesion promoter is employed in the primer compositions of this invention. In one or more embodiments, the adhesion promoter includes a non-polymeric silicon-containing hydrocarbon compound that has a lower molecular weight than the polymer having a silicon-containing hydrolysable group (i.e. the silane-terminate polymer). Also, the adhesion promoter includes at least one hydrolyzable group capable of reacting with a hydrolyzed functional group on the polymer having silicon-containing hydrolyzable terminal groups, and includes at least one moiety capable of interacting (i.e., promoting adhesion) with materials that are to be bonded with one another (such as a rubber membrane material). The expression non-polymeric, as used to modify the silicon-containing hydrocarbon compound is meant to exclude polymers and copolymers having at least 10 repeat units or monomeric units, such as urethane prepolymers having silicon-containing hydrolyzable terminal groups, but is meant to encompass oligomeric silicon-containing hydrolyzable compounds having fewer than 10 repeat units or monomers, and which are useful for promoting adhesion between a substrate and a cured adhesive composition. [0044] Suitable adhesion promoters include those having an alkoxysilyl, a ketoximesilyl, or an alkenoxysilyl group as the hydrolyzable group, and exemplary such compositions include vinyltris(2-methoxyethoxy)silane, 3- methacryloxypropyltrimethoxysilane, 2-(3,4-epoxycyclohexyl)ethyl trimethoxysilane, 3- glycidoxypropyltrimethoxysilane, 3-glycidoxypropylmethyldiethoxysilane, N-(2- aminoethyl)3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane, 3-(N- aminomethylbenzylamino)propyltrimethoxysilane, 3-mercaptopropyltrimethoxysilane, 3- aminopropyltris(methylethylketoxime)silane, 3-glycidoxy propyltriisopropenoxysilane, and 3-glycidoxypropylmethyldiisopropenoxysilane.

CHARACTERISTICS OF UNCURED PRIMER COMPOSITION [0062] According to aspects of this invention, components of the primer composition react in the presence of atmospheric moisture to form a cured coating layer (i.e. cured or crosslinked primer layer). Accordingly, aspects of the invention may be described with reference to the uncured primer composition, which refers to the composition including those constituents of the composition before appreciable chemical reaction or crosslinking takes place, and to the cured primer layer, which refers to the primer after chemical reaction or crosslinking. In one or more embodiments, the cured primer layer is the cured residue of a primer composition including a silicon-terminated polymer. Stated another way, the cured primer layer is formed from a primer composition that includes polymer with a silicon-containing hydrolysable terminal group that is curable through a moisture curing reaction. In one or more embodiments, the uncured primer composition includes greater than 95 wt %, in other embodiments greater than 98 wt %, and in other embodiments greater than 99 wt % solids. In particular embodiments, the uncured primer composition is 100% solids composition (i.e. it is solvent free). [0063] According to aspects of the present invention, the primer compositions employed in the practice of this invention are tailored to a desired dynamic and static viscosity. This can be achieved by manipulating several parameters such as, but not limited to, the molecular weight of the polymers, the amount of filler, and the use of thixotropic agents. [0064] In one or more embodiments, the primer compositions are characterized by a Brookfield Viscosity, which can be determined by ASTM D789 or D4878 using a #2 spindle at 20 r.p.m. at 23.5 °C and 50% relative humidity. In one or more embodiments, the Brookfield Viscosity (#2 spindle at 20 r.p.m.) of the curable sealant compositions is greater than 300, in other embodiments greater than 400, in other embodiments greater than 500, in other embodiments greater than 600, and in other embodiments greater than 700 centipoise. In these or other embodiments, the of the Brookfield Viscosity (#2 spindle at 20 r.p.m.) of the curable sealant compositions is less than 2500, in other embodiments less than 1500, and in other embodiments less than 1000, in other embodiments less than 900, and in other embodiments less than 800, in other embodiments less than 700, and in other embodiments less than 600 centipoise. In one or more embodiments, the Brookfield Viscosity (#2 spindle at 20 r.p.m.) of the curable sealant compositions is from about 300 to about 2500, in other embodiments from about 400 to about 1500, and in other embodiments from about 400 to about 1000 centipoise, in other embodiments from about 600 to about 900 centipoise, and in other embodiments from about 700 to about 750 centipoise. [0065] In one or more embodiments, the uncured primer compositions are characterized by a tack free time, which can be determined by ASTM C 679 at 20 °C and 50% relative humidity. In one or more embodiments, the tack free time (ASTM C679) of the uncured primer compositions is greater than 1, in other embodiments greater than 2, and in other embodiments greater than 3 minutes. In these or other embodiments, the tack free time of the uncured primer compositions is less than 1 hour, in other embodiments less than 40 minutes, in other embodiments less than 20, in other embodiments less than 15, and in other embodiments less than 10 minutes. In one or more embodiments, the tack free time of the uncured primer compositions is from about 1 to about 20, in other embodiments from about 2 to about 15, and in other embodiments from about 3 to about 10 minutes. [0066] In one or more embodiments, the primer compositions, are characterized by minimal shrinking during the curing process. As the skilled person will appreciate, shrinkage can be quantified by the percent volume change in the composition from the time of application to the time of removal of substantially all of the solvent. In one or more embodiments, the percent shrinkage of the primer compositions employed in this invention is less than 10 volume %, in other embodiments less than 5 volume %, and in other embodiments less than 3 volume %, and in other embodiments less than 1 volume %. [0067] In one or more embodiments, the primer compositions are characterized by a reduced substrate swell, particularly to EPDM membrane at 20 °C and 50% relative humidity. In one or more embodiments, the primer compositions cause an EDPM membrane to swell, after 24 hours of contact time, less than 2%, in other embodiments less than 1%, and in other embodiments less than 0.5%. [0068] In one or more embodiments, the primer compositions are characterized by a relatively low VOC release during the curing process. In one or more embodiments, the primer compositions release, up until complete cure, less than 25, in other embodiments less than 20, and in other embodiments less than 15 grams of VOC/liter of curable sealant composition. CHARACTERISTICS OF CURED PRIMER LAYER [0069] In one or more embodiments, the cured primer layer lacks adhesive qualities as compared to those layers generally known as pressure-sensitive adhesive layers. For example, a lap seam formed with just two primed surfaces and no tape or other adhesive may be characterized by a peel strength of less than 1.0 pli (1.75 N/cm). [0070] In one or more embodiments, the cured primer layer provides an advantageous surface to which an adhesive can be applied and form a bond with the adhesive that will not serve as the point of failure in a peel test; instead, the adhesive will cohesively fail or the bond between the adhesive and adjoining substrate will fail before the bond between the substrate and the primer layer. For example, the when subjected to standard peels tests, such as those prescribed by ASTM D 413, that employs EPDM substrates and a standard roofing splice tape (e.g. butyl-EPDM blend tape), the bond between the tape and the primer layer will, after 7 days aging at 20 °C and 50% relative humidity, withstand peel forces of greater than 4 pounds per lineal inch (pli), in other embodiments greater than 5 pli, in other embodiments greater than 6 pli, in other embodiments greater than 7 pli, and in other embodiments greater than 7 pli. MEMBRANE PANEL [0071] As indicated above, the methods of the present invention relate to the seaming of adjacent membranes, which may also be referred to as membrane panels. Practice of the present invention is not necessarily limited to the selection of any particular membrane panel. [0072] In one or more embodiments, the membrane panel may be a thermoset material. In other embodiments the membrane may be a thermoformable material. In one or more embodiments, the membrane may be EPDM based. In other embodiments, the membrane may be TPO based.

In other embodiments, the membrane includes thermoplastic membranes including those that meet the specifications of ASTM D-6878-03. Still other membranes may include PVC, TPV, CSPE, and asphalt-based membranes. [0073] In one or more embodiments, at least one planar surface of the membrane panel (e.g. a planar surface of an EPDM membrane panel) is coated with or includes surface particulate. In one or more embodiments, the membrane panel is an EPDM membrane panel and at least one surface, and in certain embodiments both surfaces, including mica or talc. In one or more embodiments, a substantial amount of surface particulate is present, which refers to an amount of particulate on the surface of the membrane that that would have an appreciable impact on adhesion of the membrane to an adjoining membrane. In one or more embodiments, the membrane panels include greater than 10 g/m ² , in other embodiments greater than 20 g/m ² , and in other embodiments greater than 30 g/m ² of surface particulate. [0074] In one or more embodiments, conventional dimensions characterize the roofing membrane panels. For example, in one or more embodiments, the membrane panels may have a thickness of from about 500 μm to about 3 mm, in other embodiments from about 1,000 μm to about 2.5 mm, and in other embodiments from about 1,500 μm to about 2 mm. In these or other embodiments, the membrane panels of the present invention are characterized by a width of about 1 m to about 20 m, in other embodiments from about 2 m to about 18 m, and in other embodiments from about 3 m to about 15 m. SPLICE TAPE [0075] As described above, the methods of the present invention seam together adjacent roofing membranes through the use of an adhesive that is applied to the surface of a membrane following application of the primer composition (i.e., to the primed surface). In one or more embodiments, the adhesive is a liquid contact adhesive. In other embodiments, the adhesive is a pressure-sensitive adhesive, such as a solids tape. These tapes are generally known and may be referred to as splice tape. [0076] In one or more embodiments, the splice tape may be a 100 % solids adhesive, which may also be referred to as a solid adhesive strip. In one or more embodiments, the splice tape includes butyl rubber and/or EPDM, which are often formulated with rubber tackifiers and other optional agents to impart adhesive qualities. [0077] In one or more embodiments the adhesive tapes include at least 85 percent solids, in other embodiments, at least 90 percent solids, in other embodiments, at least 95 percent solids, and in still other embodiments at least 99 percent solids. In one or more embodiments, the adhesive tape has a thickness of greater than 0.007 inches (0.178 mm), in other embodiments, greater than 0.01 inches (0.25 mm), and in still other embodiments, greater than 0.1 inches (2.54 mm). [0078] Useful adhesive tapes are disclosed in U.S. Patent Nos. 10,508,193, 6,120,869, 5,888,602, 5,859,114, 5,733,621, 5,612,141, 5,563,217, 5,545,685, 5,504,136, 5,242,727, 4,932,171, 4,849,268, 4,657,958, 4,855,172, 4,588,637, 4,539,344, and 4,426,468 which are incorporated herein by reference. Useful tapes are commercially available including those available under the tradenames QuickSeam™ (Firestone), PLIOSEAL™ (Ashland), 510™ (Adco), 505™ (Adco). INSTALLATION OF ROOF SYSTEM – FIELD APPLICATION OF PRIMER [0079] In one or more embodiments of the invention, adjacent roofing panels of a roof system can be installed on a roof surface (also known as roof substrate) and adhesively seamed (also known as splicing). Prior to seaming the adjacent membranes, a primer composition is field applied to at least a portion of the upper surface of at least one of the membrane panels (e.g. the lateral edge of at least one of the membrane panels). In a first set of embodiments, the methods of the present invention include field application of the primer composition, followed by adhesively seaming the adjacent membranes. These methods generally include, with possible variation in the order of the steps, (i) positioning membranes in an adjacent manner to provide for overlap between adjacent membranes in the lap region, (ii) securing the membrane panels to a surface of the roof, (iii) applying the primer composition of the present invention to the contact surfaces of the lap region to form primer layers, (iv) applying an adhesive to at least one of the primer layers, and (v) mating the adjacent membranes to form a lap seam. [0080] For example, according to aspects of the invention, membranes can be unrolled on a roof substrate and placed adjacent to each other with an overlap in the seam area. While this technique is well known to those skilled in the art, Fig. 1 shows an exemplary embodiment where roof system 20 includes first membrane panel 22 being partially overlapped by second membrane panel 24 in lap region 27. [0081] Practice of the present invention is not necessarily limited by the selection of any particular roof substrate to which the membranes can be attached in forming the roof systems. In one or more embodiments, the roof substrate may include the roof deck. In other embodiments, the roof substrate may include an intervening construction layer disposed above the roof deck. As the skilled person will appreciate, these intervening layers may include, but are not limited to, insulation boards, cover boards, underlayment, and existing membranes. [0082] The membrane panels are secured to the roof substrate using known techniques. For example, the membrane panels can be fully adhered to the substrate using contact adhesives. In other embodiments, a pressure-sensitive adhesive, pre-applied to the membrane, can be employed. In other embodiments, the membrane panels can be secured to the substrate using mechanical fasteners. In one or more embodiments, the membrane panels are secured or adhered to the substrate prior to forming the lap seam. For example, after securing a first membrane to the roof substrate, a second membrane is positioned adjacent to this first membrane with a portion of the second membrane overlapping the first membrane to form a lap. The second membrane is at least partially secured to the roof substrate and then the lap is seamed. In other embodiments, the lap seam is formed prior to securing or adhering the membranes to the substrate. [0083] Once adjacent membranes are positioned in the appropriate overlapping fashion, the primer composition of this invention is applied to the contact surfaces of the adjacent membranes within the lap region (i.e. the surfaces that contact each other in the formation of the seam). Application of the primer composition forms a primer layer, which may also be referred to as a primer film or a primed surface of the membrane. With reference to Fig. 1, a primer layer 26 is formed on a portion of a first surface 23 of first membrane panel 22 generally in lap area 27. And, a primer layer 28 is formed on a portion of a first surface 25 of second membrane panel 24 generally in lap area 27. Surfaces 23 can 25 may be referred to as contact surfaces. [0084] In one or more embodiments, the primer composition can be applied to the membrane panel by using conventional techniques such as brushing, spraying, and rolling. In particular embodiments, the primer composition can be applied to the lap region by employing an abrasive instrument, such as an abrasive pad, which allows for application of the primer composition by using a scrubbing technique. Methods and techniques for field application of a primer composition to the lap edge of a membrane are generally known in the art as described in U.S. Patent Nos. 5,520,761 and 5,976,292, which are incorporated herein by reference. [0085] In one or more embodiments, the primer composition is applied at a coverage rate of greater than 100, in other embodiments greater than 125, and in other embodiments greater than 150 square feet per gallon. In these or other embodiments, the primer composition is applied at a rate of less than 250, in other embodiments less than 225, and in other embodiments less than 200 square feet per gallon. In one or more embodiments, the primer composition is applied at a rate of from about 100 to about 250, in other embodiments from about 125 to about 225, and in other embodiments from about 150 to about 200 square feet per gallon. [0086] In one or more embodiments, after applying the primer composition to the membrane panel, sufficient time is provided to allow the primer to at least partially cure. In one or more embodiments, the primer composition may be subjected to heat or moisture to cause a crosslinking of one or more of the crosslinkable polymers within the primer composition. In one or more embodiments, the time period provided to allow the primer composition to cure prior to application of an adhesive is greater than 0.5 min, in other embodiments greater than 1 min, and in other embodiments greater 3 min. In these or other embodiments, the time period provided to allow the primer composition to cure prior to application of the adhesive is less than 60 min, in other embodiments less than 30 min, and in other embodiments less than 15 min. In one or more embodiments, the time period provided to allow the primer composition to cure prior to applying the adhesive is from about 0.5 to about 60 min, in other embodiments from about 1 to about 30 min, and in other embodiments from about 3 to about 15 min. [0087] As indicated above, the primer layer (e.g. layers 26, 28) is generally disposed on the surface of the membrane generally in the lap area (e.g. lap area 27 as shown in Fig. 1). The primer layer may extend beyond the lap area, but for various reasons, it may be desirable to limit the primer layer outside of the lap area. In one or more embodiments, the primer layer includes or occupies less than 20%, in other embodiments less than 10%, and in other embodiments less than 5% of the surface area of the planar surface of the membrane to which it is applied. (e.g. surface 23 of membrane 22). In these or other embodiments, primer layer is formed extending along the lateral edge of membrane panel (i.e., extends along a longitudinal length of membrane panel) and extends inwardly from the edge (i.e., perpendicular to the edge) greater than 1 cm, in other embodiments greater than 2 cm, and in other embodiments greater than 3 cm. In these or other embodiments, the primer layer extends along the lateral edge of the membrane panel and extends inwardly from the edge less than 30 cm, in other embodiments less than 20 cm, and in other embodiments less than 15 cm. In one or more embodiments, the primer layer extends along the lateral edge of the membrane panel and extends inwardly from the edge a distance of from about 1 to about 30, in other embodiments from about 2 to about 20, and in other embodiments from about 3 to about 15 cm. [0088] In one or more embodiments, the primer layers (e.g. layers 26, 28) may have a thickness of greater than 6 μm (0.25 mil), in other embodiments greater than 12 μm (0.5 mil), in other embodiments greater than 25 μm (1 mil), in other embodiments greater than 38 μm (1.5 mil), in other embodiments greater than 51 μm (2 mil), and in other embodiments greater than 64 μm (2.5 mil). In these or other embodiments, the primer layer has a thickness of less than 178 μm (7 mil), in other embodiments less than 127 μm (5 mil), and in other embodiments less than 76 μm (3 mil). In one or more embodiments, the adhesive layer has a thickness of from about 6 to about 178 μm (about 0.25 to about 7 mil), in other embodiments from about 25 to about 127 μm (about 1 to about 5 mil), and in other embodiments from about 51 to about 76 μm (about 2 to about 3 mil). [0089] Once the primer layer is formed on the contact surfaces of adjacent membranes within the lap region, an adhesive is applied for the purpose of seaming (which may also be referred to as splicing) the adjacent membranes. Where a contact adhesive is employed, the contact adhesive can be applied to one or both of the primer layers. Where a tape adhesive is employed, it is generally desirable to apply the tape to one membrane, typically the lower membrane within the splice. The positioning of the splice can be understood with reference to Fig.1, which shows tape 30 disposed between primer layers 26 and 28, which are applied to membranes 22 and 24, respectively. Specifically, primer layer 26 is applied to a portion of the upper surface 23 of membrane 22, and primer layer 28 is applied to a portion of the lower surface 25 of membrane 24. Generally, splice tapes are applied by using conventional procedures which may include manual application of the tape or by way of tape dispensing machines. Machines of this nature, which may be referred to as tape applicators, are generally known in the art as shown in U.S. Publ. Nos. 2004/0129387, 2007/0125474, 2006/0226168, and 2010/0269981, which are incorporated herein by reference. [0090] Once the adhesive is positioned, and optionally provided time to at least partially cure in the case of a contact adhesive, the seam can be formed by joining the contact surfaces to the adhesive. Where the seam tape carries a release liner, the process of the invention may include the step of removing the release liner in order to expose the adhesive. Again, with reference to Fig. 1, the adjacent membranes are positioned in overlapping fashion within the seam area to thereby sandwich the adhesive between the primer layers. Once mated, the seam can be further secured by applying pressure to the top surface of the overlapping membrane. This may include the use of rollers or other conventional tools or apparatus that allow for the efficient application of pressure to mate the membranes in the formation of a seam. [0091] The skilled person appreciates that these methods can be performed in multiple sequences. For example, the seam can be formed between the first and second membranes prior to securing the membranes to the roof substrate. Or, the first membrane secured to the substrate can be positioned in an overlapping fashion to an adjacent membrane that is subsequently set in place. In other words, those performing the installation can, as a matter of preference, elect which of the adjacent membranes form the overlapping portion of the lap. [0092] Once the seam is formed, a lap sealant may optionally be applied at the seam. For example, and with reference to Fig. 1, a lap sealant may be applied at the location 29 where membrane 24 terminates in an overlapping manner on membrane 22 (i.e. at the lap edge) and extend down to membrane 22 so as to cover and seal both primer layers 26, 28, as well as tape 30. INSTALLATION OF ROOF SYSTEM – PRE-PRIMED MEMBRANE [0093] In one or more embodiments of the invention, membrane panels that are pre- primed with the primer compositions of this invention can be received at the location of installation and installed by forming an adhesive seam between adjacent roofing panels. According to embodiments, pre-primed panels are membrane panels that have been primed with the primer composition of this invention within a fabrication facility and delivered to the location where they are to be installed. According to these embodiments, the methods of the present invention include, with possible variation in the order of the steps, (i) receiving membrane panels carrying a primer layer in a lap area of the membrane panel; (ii) positioning membranes in a manner to provide for overlap between adjacent membranes in the lap region, (iii) securing the membranes to the roof substrate, (iv) applying an adhesive to at least one of the primed surfaces, and (v) mating the adjacent membranes to form a lap seam. [0094] The pre-primed membrane panels according to embodiments of the invention can be described with reference to Fig. 2, which shows pre-primed membrane panel 50 including membrane panel 51 including top planar surface 52 and bottom planar surface 54 opposite top planar surface 52. Membrane panel 50 also includes first lateral edge 56 and second lateral edge 58 opposite first lateral edge 56, with each edge extending longitudinally down the length of the membrane. In one or more embodiments, a first primer layer 60 is disposed on top planar surface 52 along first lateral edge 56 and generally covers a lap region 63 of top planar surface 52. In one or more embodiments, a second primer layer 62 is optionally disposed on bottom planar surface 54 along second lateral edge 58 and generally a lap region 64 of bottom planar surface 54. In one or more embodiments, first primer layer 60 may optionally carry a first release liner 66 and second primer layer 62 may optionally carry a second release liner 68. The skilled person appreciates the benefits associated with application of the primer composition on top surface 52 along first lateral edge 56 and application of the primer composition on the opposite surface (i.e. bottom surface 54) along the opposite edge (i.e. second lateral edge 58), which facilitates placement of adjacent membranes in overlapping position. [0095] The characteristics of the membrane panel and the primer layer of the pre- primed membrane panels may be the same as set forth above with regard to the field applied primer embodiments described above, and therefore the description from above is incorporated into these embodiments. [0096] In one or more embodiments, the optional release liner (e.g. liner 66, 68), which may also be referred to as release member, may include a polymeric film or extrudate, or in other embodiments it may include a coated cellulosic substrate. The polymeric film or extrudate may include a single polymeric layer or may include two or more polymeric layers laminated or coextruded to one another. Suitable materials for forming a release member that is a polymeric film or extrudate include polypropylene, polyester, high-density polyethylene, medium-density polyethylene, low-density polyethylene, polystyrene or high-impact polystyrene. The coating or layer applied to the film and/or cellulosic substrate may include a silicon-containing or fluorine-containing coating. For example, a silicone oil or polysiloxane may be applied as a coating. In other embodiments, hydrocarbon waxes may be applied as a coating. As the skilled person will appreciate, the coating, which may be referred to as a release coating, can be applied to both planar surfaces of the film and/or cellulosic substrate. In one or more embodiments, the release member is characterized by a thickness of from about 15 to about 80, in other embodiments from about 18 to about 75, and in other embodiments from about 20 to about 50 μm. [0097] According to embodiments of the invention, the pre-primed membranes may be received at the location of installation in the form of a roll. The membranes can then be delivered to the roof structure and unrolled for installation. Consistent with previous embodiments, adjacent membranes can be placed in adjacent arrangement, secured to the roof substrate, and an adhesive is applied to at least one primed surface of at least one of the adjacent membranes. These steps are the same or similar to those embodiments where the primer is field applied, and therefore the description relative to the placement of the membrane, the application of the adhesive, and forming of the seam provided above with respect to those embodiments is incorporated herein. The skilled person will appreciate that where the pre-primed membranes carry a release member, which may be included to keep the primer layer clean, the method the present includes removal of the release member prior to application of the adhesive. Also, those skilled in the art will appreciate that the membrane panel, which may include a primed layer disposed on the top and bottom surfaces on opposite lateral edges, installation of the membrane panel requires proper alignment of the primed surfaces relative to the manner in which the seam will be formed. INSTALLATION OF ROOF SYSTEM – MEMBRANE COMPOSITE [0098] In one or more embodiments of the invention, membrane composite panels according to the invention can be received at the location of installation and installed by forming an adhesive seam between adjacent roofing panels. According to embodiments, membrane panels are primed with the primer composition of this invention and an adhesive is applied to the primed surface within a fabrication facility, and then the composite is delivered to the location where they are to be installed. According to these embodiments, the methods of the present invention include, with possible variation in the order of the steps, (i) receiving membrane composite panels; (ii) positioning the membrane composites in a manner to provide for overlap between adjacent membranes in the lap region, (iii) securing the membrane panels to the roof substrate, and (iv) mating the adjacent membranes to form a lap seam. [0099] The composite membrane panels according to embodiments of the invention can be described with reference to Fig. 3, which shows composite membrane panel 80 including membrane panel 81 including top planar surface 82 and bottom planar surface 84 opposite top planar surface 82. Membrane panel 80 also includes first lateral edge 86 and second lateral edge 88 opposite first lateral edge 86. In one or more embodiments, a first primer layer 90 is disposed on top planar surface 82 along first lateral edge 86 and generally covers a lap region 93 of top planar surface 82. In one or more embodiments, a second primer layer 92 is optionally disposed on bottom planar surface 84 along second lateral edge 88 and generally covers a lap region 94 of bottom planar surface 84. An adhesive layer 96 is disposed on first primer layer 90 and extends along lateral edge 86. In one or more embodiments, adhesive layer 96 carries a first release liner 102. In one or more embodiments, second primer layer 92 may optionally carry a second release liner 104. The skilled person appreciates the benefits associated with application of the primer composition on top surface 82 along first lateral edge 86 and application of the primer composition on the opposite surface (i.e. bottom surface 84) along the opposite edge (i.e. second lateral edge 88), which facilitates placement of adjacent membranes in overlapping position. [00100] The characteristics of the membrane panel, the primer layer, the adhesive tape (e.g. adhesive tape layer) and the release member may be the same as set forth above with regard to the field applied primer embodiments and pre-primed membrane embodiments described above, and therefore those descriptions from above are incorporated into these embodiments. [00101] According to embodiments of the invention, the membrane composites may be received at the location of installation in the form of a roll. The membrane composites can then be delivered to the roof structure and unrolled for installation. Consistent with previous embodiments, adjacent membranes can be placed in adjacent arrangement and secured to the roof substrate. These steps are the same or similar to those embodiments where the primer is field applied, and therefore the description relative to the placement of the membrane and forming of the seam provided above with respect to those embodiments is incorporated herein. The skilled person will appreciate that where the composite membranes carry a release member, the method the present includes removal of the release member to expose the adhesive. Also, those skilled in the art will appreciate that the membrane panel, which may include an adhesive layer disposed on the top and a primer layer on the opposed bottom surface on the opposite lateral edge, installation of the membrane panel requires proper alignment of the adhesive layer and primer layer of the adjacent membranes relative to the manner in which the seam will be formed. PREPARATION OF PRE-PRIMED OR MEMBRANE COMPOSITE [00102] As suggested above, the membrane composite panels employed in the practice of this invention may be prepared in a factory or fabrication facility prior to delivery to the location of installation. In one or more embodiments, the manufacture of the membrane composite takes place by providing a polymeric membrane panel. In one or more embodiments, the membrane panel may be provided by employing conventional techniques. For example, thermoplastic membrane panels may be formed by the extrusion of thermoplastic compositions into one or more layers that can be laminated into a membrane panel. Thermoset membranes can be formed using known calendering and curing techniques. Alternatively, thermoset membranes can be made by continuous process such as those disclosed in WO 2013/142562, which is incorporated herein by reference. [00103] As suggested above, in one or more embodiments, the primer is applied in the lap area or region of the membrane. Where the primer is factory applied, methods for providing a membrane with a factory-applied primer are generally known in the art as described in U.S. Publ. Nos. 2007/0264471, 2010/0024955, 2011/0198023, 2010/0200148, and 2013/0295295, which are incorporated herein by reference. In one or more embodiments, the primer composition is applied using conventional techniques such as by roll, slot die, spray, metering rod, or extrusion coating techniques. In particular embodiments, the primer composition is applied by spraying. For example, the composition can be sprayed by employing air, electric, hydraulic and airless spray equipment. [00104] Following application of the primer composition and, if required, a curing step or appropriate time to allowing curing, the adhesive is applied to at least one of the primer layers. Several techniques are known for the factory application of splice tape to a roofing membrane. These methods include the continuous application of tape by using automated laminating equipment. These techniques typically laminate the tape to the membrane while the membrane undergoes unrolling and subsequent rolling. Other techniques include the use of a tape dispensing apparatus on a fabrication floor within a fabrication facility. Typically, the tape carries the release liner prior to laminating the adhesive to the membrane and therefore subsequent steps of applying a release liner can be eliminated. In other embodiments, a release member is subsequently applied. Once the respective layers are applied to the membrane panel, the membrane panel is cut to length and rolled on itself for subsequent storage and shipment to the installation site. [00105] Various modifications and alterations that do not depart from the scope and spirit of this invention will become apparent to those skilled in the art. This invention is not to be duly limited to the illustrative embodiments set forth herein.
