CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Patent Application No.

61/654,907 filed on June 3, 2012, the disclosure of which is incorporated in full herein by reference.

TECHNICAL FIELD

[0002] The present disclosure relates to coating compositions comprising flaked borosilicate glass.

BACKGROUND

[0003] Historically, coatings have been utilized to protect an underlying material and/or to impart desirable surface properties, for example, color and/or gloss, thereto. Glass materials have also been added to coatings, such as paints, to impart fire resistant properties. For example, glass beads have been added to paints, such that when exposed to high heat or flame, the glass beads can melt and provide a flame resistant barrier. Glass materials, such as hollow glass spheres, have also been added to reduce the density of paints and coating materials.

[0004] It would be advantageous if a coating could impart other functional properties to a substrate or article, such as, for example, thermal management properties. These needs and other needs are satisfied by the compositions, methods, and products of the present disclosure.

SUMMARY

[0005] In one aspect, a surface coated with a coating composition to form a coated surface is provided. The coating composition includes a coating matrix and a quantity of flaked borosilicate glass. Upon exposure of the coated surface to sunlight or heat, the quantity of flaked borosilicate glass in the coating composition is effective such that the coated surface exhibits a cooler temperature than a temperature of a comparable uncoated surface, similarly exposed to sunlight or heat, but that does not comprise the coating composition.

[0006] In another aspect, a method for cooling a surface is provided. The method includes applying a coating composition to the surface to form a coated surface. The coating includes a quantity of flaked borosilicate glass and a coating matrix. The coated surface is then exposed to sunlight or heat. Upon exposure of the coated surface to sunlight or heat, the quantity of flaked borosilicate glass in the coating composition is effective such that the coated surface exhibits a cooler temperature than a temperature of a comparable uncoated surface, similarly exposed to sunlight or heat, but that does not comprise the coating composition.

[0007] In still another aspect, a structure is provided. The structure includes a structural substrate with an exterior surface. A material layer is affixed to the exterior surface of the structural substrate. The material layer includes a first surface that is at least partially coated with a coating composition. The coating composition includes a quantity of flaked borosilicate glass. Upon exposure of the at least partially coated first surface to sunlight or heat, the quantity of flaked borosilicate glass in the coating composition is effective such that the at least partially coated first surface exhibits a cooler temperature than a temperature of a surface of a comparable uncoated material layer, similarly exposed to sunlight or heat, but that does not comprise the coating composition.

[0024] Coating Compositions

[0025] The coating compositions of the present disclosure comprise flaked borosilicate glass. In one aspect, the addition of a flaked borosilicate glass composition to a coating can improve the ability of the resulting coating to dissipate, move, and/or remove heat from an underlying substrate when exposed to sunlight or heat. The coating composition may provide improved thermal management properties, when applied to a substrate or a surface, as compared to a substrate or a surface without the coating composition. Without being bound to any one theory, the coating composition reduces the amount of thermal energy absorbed by the coated substrate or surface. In one aspect, a coated substrate or surface can remain at about ambient temperature upon exposure to thermal radiation, for example, solar, infrared, convective, or a combination thereof. In another aspect, the coating composition may reduce the amount of thermal radiation absorbed by an underlying substrate or surface. In another aspect, upon exposure to sunlight or heat, the portion of a substrate or a surface comprising the coating composition may exhibit a temperature that is about 5 ° F to about 50 ° F, about 10 ° F to about 40 ° F, about 15 ° F to about 30 ° F, about 20 ° F to about 30 ° F, or about 25 ° F cooler than a comparable uncoated substrate or surface.

[0026] The coating composition of the present disclosure comprises a coating matrix and an effective amount of flaked borosilicate glass. As used herein, the term "coating composition" is intended to refer to a mixture of coating components, such as, for example, flaked borosilicate glass and a vehicle and/or resin system, prior to drying and/or curing to form a coating. As used herein, "coating matrix" refers to any other components that are present in a cured and/or dried form of the coating composition, and may comprise anything except the flaked borosilicate glass. Similarly, the terms "coated," "coating" and "coated surface" are intended to refer to a cured and/or dried form of the coating compositions. It should be understood that a coating formed from a coating composition will typically comprise the same components as the coating composition, except for any volatile components that can evaporate, and/or any components that cross-link or react with other components, a substrate, or a combination thereof.

[0027] In some embodiments, the coating compositions may improve the thermal properties of the coated surface or coated structure, relative to a comparable uncoated surface or uncoated structure. In an embodiment, the coating compositions are, upon exposure to heat, sunlight, or solar radiation, effective to impart a thermal emittance in the range of about 0.5 and about 0.95, about 0.5 and about 0.85, about 0.5 and about 0.75, about 0.6 to about 0.75, or about 0.65 to about 0.75.

In other embodiments, the coating compositions are effective such that absorbed incident infrared, solar, or heat radiation is radiatively emitted from the coating composition (and coated surface or coated structure) at a lower energy than the absorbed incident radiation.

[0029] In certain embodiments, the coating composition, after drying and/or curing, consists essentially of a coating matrix and a flaked borosilicate glass.

[0030] In one embodiment, a surface coated with a coating composition to form a coated surface is provided. In embodiments, the surface includes, but is not limited to, roofing shingles, roofing granules, and/or carbon nanotubes. Upon exposure of the coated surface to sunlight or heat, the quantity of flaked borosilicate glass in the coating composition is effective such that the coated surface exhibits a cooler temperature than a temperature of a comparable uncoated surface, similarly exposed to sunlight or heat, but that does not comprise the coating composition.

[0031] In some embodiments, the coating composition applied to a surface or a substrate forms a coated surface or coated substrate with a low amount of solar reflectance. In some embodiments, the amount of solar reflectance is less than about 50%, less than about 40%, less than about 30%, or less than about 20%.

In still other embodiments, the amount solar reflectance of a coated substrate or a coated surface may be the same amount of solar reflectance as a comparable uncoated substrate or uncoated surface, respectively.

[0032] In some embodiments, the coating matrix may comprise a paint, such as, for example, a latex paint, an alkyl paint, an acrylic paint, or a combination thereof. In a specific embodiment, the coating matrix comprises a latex paint. In other aspects, the coating matrix may comprise an epoxy, an elastomeric material, or a crosslinkable material. In other aspects, the coating matrix may comprise other resin systems or components that can for a coating upon, for example, curing and/or drying.

[0033] In one aspect, the coating matrix does not comprise a pyrolyzed carbon containing ionic species. In still other aspects, the coating matrix does not comprise one or more of a clay, a binder material, or a combination thereof.
