AND METHOD OF USING THE SAME

BACKGROUND

In normal use, surfaces of motor vehicles, for example, are regularly exposed to weather effects such as rain, snow, sleet, ice formation, and other precipitation, as well as environmental contaminants (e.g., dirt, grime, dust, air-borne pollutants, road surface residue, and bird and other animal waste). It is desirable to maintain the physical condition of these vehicles by cleaning or washing them and, in some cases, subsequently waxing and polishing or buffing them.

Many products that are intended to improve or restore a vehicle's finish are commercially available. A coating composition said to be useful for imparting water repellency, gloss, and durability to a surface, particularly on an automobile or other vehicle is described in U.S. Pat. Appl. Pub. No. 2017/0349783 (Kirino). A highly abrasion-resistant vehicle paint is described in U.S. Pat. Appl. Pub. No. 2011/0082254 (Sepeur et al.).

Certain compositions including polyorganosiloxanes having hydrolyzable groups have been reported to be useful for automotive coatings and are described in U.S. Pat. No. 9,334,408 (Onai), U.S. Pat. Appl. Pub. No. 2008/0026163 (Hamaguchi et al.), Int. Pat. Appl. Pub. No. WO 2014/120601 (Harkness et al.), and Japanese Patent Application 2018/080291 A, published May 24, 2018.

SUMMARY OF THE DISCLOSURE

In one aspect, the present disclosure provides a first polyorganosiloxane and at least one of an amino- functional silane or a cyclic azasilane. The first polyorganosiloxane has divalent units represented by formula: and greater than two -Si(Y) _p (R) _3-p groups. In the first polyorganosiloxane, each R is independently alkyl, aryl, arylalkylenyl, or heterocycloalkylenyl, wherein alkyl and arylalkylenyl are unsubstituted or substituted with halogen and optionally interrupted by at least one catenated -O-, -S-, -N(R ¹¹ )-, or combination thereof, wherein aryl, arylalkylenyl, and heterocycloalkyenyl are unsubstituted or substituted by at least one alkyl, alkoxy, halogen, or combination thereof, and wherein R ¹¹ is hydrogen, alkyl, aryl, or arylalkylenyl, wherein aryl and arylalkylenyl are unsubstituted or substituted by at least one alkyl, alkoxy, or combination thereof; each Y is independently a hydrolysable group; and p is 1, 2, or 3. The amino-functional silane is represented by formula (R ⁶ ) ₂ N-[R ⁴ -Z] _r -R ⁴ -[Si(Y) _p (R ⁵ ) _3-p ], and the cyclic azasilane is represented by formula

In these formulas, each R ⁴ is independently alkylene, arylene, or alkylene optionally interrupted or terminated by arylene; R ⁵ is alkyl, aryl, arylalkylenyl, or heterocycloalkylenyl, wherein aryl and arylalkylenyl are unsubstituted or substituted by at least one alkyl, alkoxy, or combination thereof; each Z is independently -O- or -N(R ⁶ )-; each R ⁶ is independently hydrogen, alkyl, aryl, arylalkylenyl, or -R ⁴ -[Si(Y) _p (R ⁵ ) _3-p ], wherein aryl and arylalkylenyl are unsubstituted or substituted by at least one alkyl, alkoxy, or combination thereof; R ⁷ is an alkylene having 2 to 5 carbon atoms and is uninterrupted or interrupted by at least one catenated -N(R ⁸ )-; each R ⁸ is independently hydrogen, alkyl, or alkenyl, wherein are unsubstituted or substituted by -NR'R ² . wherein R ¹ and R ² are independently hydrogen or alkyl; each Y is independently a hydrolyzable group; r is 0, 1, 2, or 3; and p is 1, 2, or 3.

In another aspect, the present disclosure provides a method of making a coated article. The method includes applying the aforementioned composition on at least a portion of a surface of a substrate and allowing or inducing the composition to at least partially cure to form a first coating on at least a portion of the surface of the substrate.

In some embodiments, compositions of the present disclosure can provide high receding contact angles to water and low coefficients of friction even after scrubbing. The ability for the compositions to maintain such properties is surprisingly better than comparative compositions that have only two -Si(Y) _p (R) _3-p groups.

As used herein:

The term “aliphatic group” means a saturated or unsaturated linear, branched, or cyclic hydrocarbon group. This term is used to encompass alkyl, alkenyl, and alkynyl groups, for example.

The term “alkyl” refers to a monovalent group that is a radical of an alkane and includes straight- chain, branched, cyclic, and bicyclic alkyl groups, and combinations thereof, including both unsubstituted and substituted alkyl groups. Unless otherwise indicated, the alkyl groups typically contain from 1 to 30 carbon atoms. In some embodiments, the alkyl groups contain 1 to 20 carbon atoms, 1 to 10 carbon atoms, 1 to 6 carbon atoms, 1 to 4 carbon atoms, or 1 to 3 carbon atoms. Cyclic groups can be monocyclic or polycyclic and typically have from 3 to 10 ring carbon atoms. Examples of “alkyl” groups include methyl, ethyl, n- propyl, n-butyl, n-pentyl, isobutyl, t-butyl, isopropyl, n-octyl, n-heptyl, ethylhexyl, cyclopentyl, cyclohexyl, cycloheptyl, adamantyl, and norbomyl.

The term "alkylene" is the divalent or trivalent form of the "alkyl" groups defined above.

The term “amino group” is a functional group that consists of a nitrogen atom attached by single bonds to hydrogen atoms, alkyl groups, aryl groups, or a combination of these three. Primary amino groups include two hydrogen atoms bonded to the nitrogen, secondary amino groups include one hydrogen atom bonded to the nitrogen, and tertiary amino groups include no hydrogen atoms bonded to the nitrogen.

The term “aryl” refers to a monovalent group that is aromatic and, optionally, carbocyclic. The aryl has at least one aromatic ring.

In some embodiments, the organic solvent is a non-halogenated organic solvent having a boiling point of at least 160 °C. Non-halogenated organic solvents include organic solvents that do not include halogen atoms (e.g., chlorine, bromine), such as halogenated solvents like 1,2-dichlorobenzene.

In some embodiments, the composition of the present disclosure has a volatile organic content (VOC) of no more than 750 grams per liter (g/L) (or no more than 500 g/L, or no more than 250 g/L). In this context, the terms “volatile organic content” and “VOC” refer to the volatility of the composition as measured by ASTM D6886-18 (Standard Test Method for Determination of the Weight Percent Individual Volatile Organic Compounds in Waterborne Air-Dry Coatings by Gas Chromatography). This test uses methyl palmitate as a reference marker. A compound that elutes prior to the marker is considered VOC while a compound that elutes after the marker is not considered VOC. A “non-VOC” compound refers to a compound that elutes after the methyl palmitate marker.

The amount of solvent, if present, should be sufficient to prevent the composition from evaporating too quickly during application, which may cause the composition to have a streaky appearance or otherwise make it difficult to wipe off any excess composition. Too much solvent may evaporate too slowly or making the composition difficult to apply. In some embodiments of the composition of the present disclosure, the composition includes at least 1 wt. %, at least 5 wt. %, or at least 10 wt. % of at least one organic solvent and/or siloxane solvent, based on the total weight of the composition. In some embodiments, the composition includes up to 99 wt. %, up to 95 wt. %, or up to 90 wt. % of at least one organic solvent and/or siloxane solvent, based on the total weight of the composition. In some embodiments, the composition includes not more than 25 wt. %, 20 wt. %, 15 wt. %, 10 wt. %, 5 wt. %, 4 wt. %, or 1 wt. %, organic solvent and/or siloxane solvent, based on the total weight of the composition. The organic and siloxane solvents can be any of those described above in any of their embodiments.

The composition of the present disclosure can include other components to impart particular desired properties. The composition can include conventional additives such as initiators, emulsifiers (including surfactants), stabilizers, anti-oxidants, flame retardants, adhesion promoters (for example, alkoxysilanes), release modifiers (for example, silicate resins including silicate MQ resin), colorants, thickeners (for example, carboxy methyl cellulose (CMC), polyvinylacrylamide, polypropylene oxide, polyethylene oxide/polypropylene oxide copolymers, polyalkenols), and combinations thereof. In some embodiments, the composition is substantially free of surfactant (that is, it has less than 1, 0.5, 0.1, or 0.05 % by weight surfactant, based on the total weight of the composition.) In some embodiments, compositions according to the present disclosure comprise water. In some embodiments, the water is present in the composition in a range from 0.01 percent to 5 percent (in some embodiments, 0.05 to 1, 0.05 to 0.5, or 0.1 to 0.5 percent) by weight, based on the total weight of the composition. Water may be added to the composition or may be added as part of an aqueous acidic solution (e.g., concentrated hydrochloric acid is 37% by weight of the acid in water). However, we have found that it is typically not necessary to add water to the compositions described herein. The water useful for hydrolysis of the silane groups may be adventitious water in the solvent or adsorbed to the surface of the substrate or may be present in the atmosphere to which the amino-functional compound and the polyorganosiloxane are exposed (e.g., an atmosphere having a relative humidity of at least 10%, 20%, 30%, 40%, or even at least 50%). The low amount of water can be beneficial to the shelf-stability of some embodiments of the composition of the present disclosure.

In some embodiments, the composition of the present disclosure can be an emulsion (e.g., an oil-in water emulsion). In these embodiments, the composition can include up to 99 wt. %, up to 95 wt. %, or up to 90 wt. % water, based on the total weight of the composition. In some of these embodiments, the composition includes at least 50 wt. %, at least 60 wt. %, or at least 75 wt. % water, based on the total weight of the composition. Purified or deionized water may be useful.

Emulsions typically include an emulsifier. A wide variety of surfactants can be useful as emulsifiers. In some embodiments, the emulsifier includes at least one of a nonionic surfactant or an anionic surfactant.

In some embodiments, the emulsifier includes a nonionic surfactant and optionally an anionic surfactant. Suitable nonionic surfactants include polyoxyethylene (POE) and polyoxypropylene (POP) aliphatic ethers having a linear or branched chain with 12 to 20 carbon atoms. The surfactant may include both POE and POP units in a random or block form. The surfactant may contain 1 to 100, 3 to 50, or 5 to 20 POE or POP units or a combination thereof. Suitable examples include POE (4 to 11) lauryl ether, POE (10 to 20) cetyl ether, POE (4 to 20) oleyl ether, POP (5) lauryl ether, POP (7) cetyl ether, POP (10) oleyl ether, and POE (3) POP (5) lauryl ether, wherein the numerical values in parentheses of POE and POP indicate the number of units of oxyethylene unit and oxypropylene unit. In some embodiments, the nonionic surfactant is an alcohol ethoxylate. Examples of suitable anionic surfactants include sulfates of polyethoxylated derivatives of straight or branched chain aliphatic alcohols and carboxylic acids. The anionic surfactant can be the sulfate of any of the polyethoxylated derivatives of straight or branched chain aliphatic alcohols described above. Suitable surfactants are available from a variety of commercial sources. In some embodiments, the surfactant comprises at least one of a five-mole ethoxylate of a linear, primary 12-14 carbon number alcohol available, for example, from Huntsman Corporation, The Woodlands, Tex., under the trade designation “SURFONIC L24-5” Surfactant, an alcohol ethoxylate available, for example, from Dow Chemical Company under the trade designation “ECOSURF EH-6”, and a sodium salt of a fatty alcohol polyglycol ether sulphate, available, for example, from BASF Corporation, Florham Park, N.J., under the trade designation “DISPONIL FES 32IS”

In some embodiments, the emulsion composition can include up to 10 wt. % or up to 8 wt. % of a surfactant, including any of those described above, based on the total weight of the emulsion. In some embodiments, the emulsion composition includes at least 0.50 wt. % or at least 1 wt. % of a surfactant, including any of those described above, based on the total weight of the emulsion. In some embodiments, the emulsion composition can include up to 10 wt. % or up to 8 wt. % of reactive ingredients, including the first polyorganosiloxane, the amino-functional silane, the silane having at least one hydrolyzable group, and the catalyst as described above in any of their embodiments, based on the total weight of the emulsion.

In some embodiments, the emulsion composition includes at least 1 wt. %, at least 3 wt. %, or about 5 wt. % of these reactive ingredients as described above in any of their embodiments, based on the total weight of the emulsion.

The composition of the present disclosure can be free of fluorinated silanes, for example, having a structure represented by formula RF-Q-Si(Y) _p (R) _3-p or (Y) _p (R) _3-p Si-Q-RF-Q-Si(Y) _p (R) _3-p , wherein RF is a monovalent or divalent fluoroalkyl group or a perfluoropolyether group, and Q, Y, R, and p are as defined above in any of their emboidments. In some embodiments, the composition is substantially free of these fluorinated silanes (that is, it has less than 1, 0.5, 0.1, or 0.05% by weight fluorinated silane, based on the total weight of the composition.

The composition of the present disclosure can be prepared by combining the various components, in some embodiments, with agitation or stirring. The composition can be maintained as a relatively shelf-stable, two-part system (for example, by keeping the catalyst separate from the polyorganosiloxane and other silane compounds), if desired, but a one-part system (comprising the catalyst, polyorganosiloxane, amino-functional silane, cyclic azasilane, and optionally other silanes and siloxanes) can also be stable (such that there is no gelling or precipitation, for example) for periods of at least two months, and often up to one year, or five years, or even longer if packaged to exclude moisture before coating or otherwise applying the composition. When the composition is an emulsion, its shelf life can be maximized by storing it sealed at room temperature in a container with minimal headspace and avoiding exposing it to ambient air. The container can be purged with inert gas before filling. Utilization of a ventless sprayer to apply the composition may also be useful.

A variety of methods may be useful for applying the composition. Typically, and advantageously, a small amount of coating composition can be applied to the surface to be treated. For example, approximately 6 drops/ft ² (65 drops/m ² ) may be used, depending on the condition of the surface being treated (weathered or deteriorated surfaces may benefit from using a larger amount of the coating composition). The composition may be applied to a surface either directly using a variety of techniques (e.g., spraying), or the composition may be first applied to a spreading device (e.g., a cloth) and then applied to a surface. In one convenient approach, the coating compositions may be evenly distributed on a surface by hand-wiping with a clean, dry cloth or pad (e.g., a suede or microfiber cloth, a foam pad, or a combination thereof) using, for example, overlapping circular strokes.

In some embodiments of the method of making a coated article of the present disclosure, the method comprises allowing or inducing the coating composition to at least partially cure. In some embodiments, at least 0.1 minute, at least 1 minute, from two to five minutes, or no more than 30 minutes after the composition is applied, excess composition may be wiped off and the coating allowed to further cure. In some embodiments, at least 0.1 minute, at least 1 minute, from two to five minutes, or no more than 30 minutes after the composition is applied, excess composition may be wiped off, and the composition can be applied again. In some embodiments, the composition is allowed or induced to cure for 30 seconds to 30 minutes before the excess is wiped off. In some embodiments, cure conditions of 70°F ± 5°F (21.1°C ± 2.8°C) and 50% ± 3% relative humidity are used. Shorter or longer curing times may be used if desired by the user. The composition may then be allowed to cure for up to 10 days, 7 days, 3 days, 5 days, one day, or one hour at 70°F ± 5°F (21.1°C ± 2.8°C) and 50% ± 3% relative humidity. In some embodiments, multiple coats are applied, allowing a three-day cure for each coat.

In some embodiments of the articles of the present disclosure and/or made by the method of the present disclosure, the composition provides a clear, streak-free, and in some cases, a glass-like, finish on the coated surface.

In some embodiments of the articles of the present disclosure and/or made by the method of the present disclosure, the composition provides excellent water-beading on substrate surfaces, encouraging a large number of well-rounded, hemispherical water drops to form or “bead up.” Advantageously, these drops often easily roll off the car, carrying and dirt or debris with them. Thus, compositions described herein may promote faster drying and a self-cleaning property of a surface that subsequently becomes wet.

In some embodiments of the articles of the present disclosure and/or made by the method of the present disclosure, the composition facilitates the release of water from surfaces. Water applied to such a surface (for example, from precipitation or rinse water used to wash and clean a substrate surface) will be readily released from or “run off' the surface, thereby reducing the water marks or water spots that may have to be removed once any water that remains on the coated surface evaporates.

Desirably, the composition typically provides sufficient durability to maintain acceptable performance and a desired appearance even after the coated surface has been subjected to repeated washing and rinsing cycles. For example, a motor vehicle panel that has been treated according to some embodiments of the present disclosure may still promote excellent water-beading, encouraging a large number of small, well-rounded, hemispherical water drops to form or “bead up” even after more than 100 back-and-forth wiping motions (cycles) with a soft foam pad that has been saturated with a 9% aqueous automotive shampoo solution, or more than 200 cycles, or more than 250 cycles.

In some embodiments, an article is prepared as described herein using the Test Panel Coating Method in the Examples Section, wherein a first coating composition is applied twice and each time allowed to cure for 45 seconds before the excess coating solution is removed, with 60 minutes between coats, and the second application allowed to further cure for 30 minutes before application of the second coating composition. In the Panel Coating Method, the second coating composition is allowed to cure or dry for 30 minutes before excess solution is removed and then allowed to further cure or dry for 72 hours in a controlled temperature and humidity room set at 72 °F and 50% relative humidity. In some embodiments, the articles prepared in this manner display at least one of the following properties: a Coefficient of Friction of less than 0.1 measured according to the Coefficient of Friction Test Method in the Examples Section; a Coefficient of Friction of less than 0.15 after 500 scrubs (made according to the Panel Scrub Test Method in the Examples Section; a receding contact angle of greater than 90 degrees measured according to the Water Contact Angle Test Method of the Examples Section; a receding contact angle of greater than 80 degrees after 500 scrubs (made according to the Panel Scrub Test Method in the Examples Section) measured according to the Water Contact Angle Test Method in the Examples Section; and a receding contact angle of at least 70 degrees after being submerged in 90 °C water for two hours (made according to the Hot Water Test Method in the Examples Section) measured according to the Water Contact Angle Test Method in the Examples Section.

In some embodiments, the substrate of the article of the present disclosure and/or made by the method disclosed herein includes glass, plastic, rubber, wood, gel-coat, leather, fiberglass, fabric, metal, a painted surface, a polymeric film, or a combination thereof. In some embodiments, the substrate is transparent. Plastics useful as a substrate include polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), polycarbonate, and mixtures thereof. Carbon and graphite fibers and other materials can be useful as reinforcing agents in plastic composites. Both ferrous and nonferrous metal surfaces useful as a substrate in the method and article of the present disclosure. Examples of useful metals include aluminum, brass, bronze, chrome, copper, tin, zinc, iron, stainless steel and steel. Painted metal substrates and bare metal substrates may be useful substrates, depending on the desired application. Polymeric films useful as substrates in the article and method of the present disclosure include car wrap films. Examples of useful polymeric films include polyurethane films and vinyl (PVC) films. In addition, while the various embodiments have particular utility for motor vehicles, other applications are contemplated such as use on surfaces associated with marine and aerospace environments, household uses (e.g., tub and shower enclosures), and for building maintenance (e.g., windows).

Test Methods and Preparation Procedures

Fluid Contact Angle Test Method.

Fluid contact angles of each sample were measured using a Rame-Hart goniometer (Rame-Hart Instrument Co., Succasunna, New Jersey). Advancing (q _adv ) and receding (q _rec ) angles were measured as fluid (deionized water unless otherwise specified) was supplied via a syringe into or out of sessile droplets (drop volume about 5 mL). Measurements were taken at three different spots on each coated ACT test panel surface, and the reported measurements are the averages of the six values for each sample (a leftside and right-side measurement for each drop). The probe fluid used in this test was deionized water. Contact Angle hysteresis (q _hys ) was determined using the following equation: q _hys = q _adv - q _rec . Coefficient of Friction (COF) Test Method.

In a controlled temperature humidity room (72°F, 50% RH), a coated ACT Test Panel, as described below, was secured on top of a IMASS SP2000 available from IMASS, Accord, Massachusetts using the appropriate panel clips included with the IMASS. A friction sled with tether available from IMASS, Part # SP-101038, was modified by wrapping a pre-cut 2.5 in (6.4 cm) x 8 in (20.3 cm) TX300 cotton wipe, available from from Tex Wipe, around the sled. A small slit was cut into the wipe to allow the tether to be exposed. The wipe was further secured with 233+ masking tape available from 3M Company. The modified friction sled was then attached to the IMASS SP2000 by the provided tether and the sled was placed onto the coated ACT test panel with the tape side up. The IMASS SP2000 settings were adjusted in the setup menu to the following: Sled Weight: 200g; Initial Delay: 2 seconds; Averaging Time: 5 seconds; Units: In/Min; Testing Speed: 6 inches per minute (in/min). After the instrument was set up, samples were tested 3 times (15 seconds total) and the kinetic potential (KP) results were averaged.

Panel Scrub Method.

Panel scrub testing was performed by securing a a coated ACT Test Panel, as described below, into a BYK Gardner Scrub machine available from BYK Gardner USA. The scrub machine was equipped with the sponge holder attachment that was modified with an extra 500 grams (g) of weight. Total weight of the holder was ~ 940 g.

Two 4.7 in (11.9 cm) x 3.0 in (7.6 cm) x 0.6 in (i.5 cm) sponge available under the trade designation “OCELO” from 3M company, were cut to fit within the sponge holder. Approximately 500 mL of a prediluted (10:1 ratio with water) Super Degreaser, Meguiar's D108 available from Meguiar's, Inc., was poured into the sample tray until the test panel was submerged in cleaner. The test panels were scrubbed using the scrub machine at a rate of 40 cycles/min for a total of 500 cycles. Contact angle measurements and Coefficient of Friction measurements were measured before and after scrubbing.

NMR Spectroscopy.

An Ultrashield 500 Plus FT NMR instrument from Bruker (Billerica, MA) was used to acquire ¹ H NMR (500 MHz) ¹³ C NMR (125 MHz) and ²⁹ Si NMR (99.36 MHz) spectra. ¹ H and ¹³ C samples were dissolved in CDCl ₃ . ²⁹ Si NMR was performed on samples that were dissolved in a solution of 0.04M Cr(acac) ₃ in CDCI ₃ . Synthesis of Polymer 1 :

S-15 (50 grams (g)) and MTS (40.8 g) were added to a 250 mL round bottom flask with magnetic stirring and nitrogen flow over it, and DHA (0.06 g) and EHA (0.06 g) were added. The clear mixture was stirred and heated to 70° C for 15 hours. Remaining volatile components of the mixture were then removed by rotary evaporation at 50° C, 30 min, 17 mbar. ²⁹ Si NMR indicated the disappearance of the O-Si(CH ₃ ) ₂ -OH resonance at ~ -10 ppm, and the appearance of a -O-Si CH ₃ (O CH ₃ ) ₂ resonance at -48 ppm. The formula of the polymer was determined to be (CH ₃ O) ₂ (CH ₃ )Si-O-[Si(CH ₃ ) ₂ -O] _34.8 -Si(CH ₃ )(OCH ₃ ) ₂ , as determined from NMR spectroscopy.

Synthesis of Polymer 2

ViTMS (14.8g) and Pt-DVTMS (0.5 g) were added to a 100 mL round bottom flask and heated to 70° C under magnetic stirring. HMS-151 was added dropwise, and an exotherm was observed. The mixture was stirred 2 hours at 70° C after the addition of the HMS-151, and then remaining volatile components of the mixture were then removed by rotary evaporation at 50° C, 30 min, 17 mbar. ²⁹ Si NMR indicated the disappearance of the O-Si(CH ₃ )(H)-O resonance from -34 - -38 ppm, and the appearance of -CH ₂ -Si(O CH ₃ ) ₃ resonance at -40 - -44 ppm. The formula of the polymer was calculated to be

(CH ₃ ) ₃ Si-O-[Si(CH ₃ ) ₂ -O] _25.6 -[Si(CH ₃ )(CH ₂ CH ₂ Si(OCH ₃ )3)-O] _7.0 -Si(CH ₃ ) ₃ , as determined from NMR spectroscopy.

Panel Preparation:

Black painted steel panels with OEM-style pre-treatments and paint were used as substrate for the coating. These were purchased from ACT Test Panels, LLC 273 Industrial Dr., Hillsdale, MI 49242. The original Item Number for said panels is 59597 having dimensions of 18 inch (48 cm) x 24 inch (61 cm) x 1/32 inch (0.079 cm). Panels that had been used previously for fine abrasive testing were employed.

Before painting, the painted side of the panels was sanded using a Festool air driven dual action sander with 5mm throw, 6 inch (15 cm) diameter backup pad, interface pad and a 3M™ Hookit™ Purple Clean Sanding Abrasive Disc, grit P400, available from 3M Company, St. Paul, Minnesota. The abraded surface was hand cleaned by wiping with a paper toweling wetted with SWX350 H2 O-SO-CLEAN WATERBORNE PRE-CLEANER, available from PPG, Pittsburg, Pennsylvania, followed by an additional cleaning pass using a clean microfiber cloth wetted with the same cleaning solvent. This two-step cleaning process was repeated. This was followed by a three-pass cleaning procedure using SX330 ACRYLI-CLEAN WAX AND GREASE REMOVER, available from PPG, in place of SWX350, using the previously described paper towels and cloth. A final cleaning pass was made with a DYNATRON 823 TACK CLOTH, available from the 3M Company, to remove any remaining dust and debris.

Using an ACCUSPRAY SPRAY GUN SYSTEM, from 3M Company, having a 1.4 mm tip at 20 psi gun pressure and a 3M PPS PAINT PREPARATION SYSTEM, from 3M Company, a sealer layer was first applied to the panel. The sealer was prepared by blending, in a 3M PPS paint cup, DAS3025 (sealer), DCX3030 (catalyst) and DT885 (reducer), all available from PPG, in a 3:1:1 ratio by volume. The coated sealer was allowed to flash dry for 10 minutes before applying a basecoat.

Using a SATA 5500 RP paint spray gun, available from SATA GmbH & Co. KG, Komwestheim, Germany, with a 1.3 mm tip at 27 psi gun pressure and a 3M PPS PAINT PREPARATION SYSTEM, a basecoat layer was next applied. The basecoat was prepared by blending, in the 3M PPS paint cup, DBC9700, available from PPG, and DT885 (reducer) in a 1:1 ratio by volume. This was applied in two coats separated by 5 minutes between coats and then the basecoat was allowed to dry 10 minutes before a clearcoat was applied.

Using the SATA 5500 RP paint spray gun, with a 1.3mm tip at 32 psi gun pressure and a 3M PPS PAINT PREPARATION SYSTEM, a clearcoat layer was applied. The clearcoat was prepared by blending, in a 3M PPS paint cup, EC530 (clearcoat), ECH5075 (catalyst) and ECR75 (reducer), all available from PPG, in a 3:1:1 ratio by volume. The clearcoat was applied in two coats separated by 10 minutes between coats. The coated panels were then baked in a paint booth for 40 minutes at 155°F booth temperature after clear coat application. The stated bake time includes time for temperature ramp from about 75°F to the 155° setpoint. Panels were stored at room temperature for 3 weeks, and then placed in an 180°F oven for 4 hours.

Prior to coating with a composition of the present disclosure, the modified test panels (as described above) were prepped as follows: approximately 1.0 g of Meguiar's M205 mirror glaze, available from Meguair's, Inc., Irvine, CA, was spread evenly onto a Meguiar's Soft Buff DA Foam Polishing Disc, 6 in (15.2 cm), which was attached to a Meguiar's MT300 dual action polisher set to 5200 revolutions per minute (rpm). Using moderate pressure, each ACT test panel was polished for 1 minute. After polishing, the residue remaining on the panel was cleaned off using a 3M microfiber towel (PN 39016) available from 3M Company, and Foaming Aerosol Glass Cleaner (PN 08888) available from 3M Company.

Examples 1 - 5 (Ex. 1 - Ex. 5) and Comparative Examples 6 - 9 (CE-6 - CE-9)

The formulations for Ex. 1 - Ex. 8 are shown in Table 2. The examples were prepared by mixing the indicated components in 20 mL glass vials. The solutions were then coated on the previously prepared panels using the following procedure. A 4 in (10.2 cm) x 4 in (10.2 cm) YS01 cloth (80% polyester, 20% polyamide 190 GSM Suede microfiber), available from S.Y. Vina Joint-Stock Company, Nhon Trach IZ 2, Nhon Trach - Dong Nai, Vietnam, was wrapped around a 1.5 in (3.8 cm) x 3 in (7.6 cm) foam block available from Detailing.com (item # GYE-FOAMBLOCK). Approximately 0.5 milliliter (mL) of a solution was applied to the cotton cloth wrapped foam block and then applied, via wiping for 30 seconds, onto a panel. The coated panel was allowed to cure for 45 seconds before the excess coating solution was buffed off of the panel using a detailing cloth available under the trade designation “PERFECT-IT DETAILING CLOTH”, PN 06016, available from 3M Company. Each panel was coated twice with the solution waiting 60 minutes between coats.

After the second coat was applied to the panel, the panel was allowed to further cure for 72 hours in a controlled temperature and humidity room set at 72°F and 50% relative humidity. After 72 hours, the panels were tested using the test methods described below.
