| 20080289968 | METHOD OF COATING A SUBSTRATE INCLUDING A SIMULTANEOUS CURE - A method of coating a substrate includes the steps of applying an electrocoat to the substrate, applying a powder primer onto the electrocoat, and then applying a topcoat onto the powder primer. The topcoat typically includes a powder basecoat and a clearcoat. The powder primer is applied to the electrocoat without first curing the electrocoat before application of the powder primer. The powder basecoat is applied to the powder primer without first curing the powder primer before application of the powder basecoat. The clearcoat is applied over the powder basecoat after which the electrocoat, the powder primer, the powder basecoat, and the clearcoat are simultaneously cured in an oven. | 11-27-2008 |
| 20090044724 | COATING COMPOSITIONS CONTAINING MONOMERIC, LONG-CHAIN REACTANTS - A coating composition is disclosed comprising a binder, the binder comprising a crosslinker, a thermosetting polymer reactive with the crosslinker, and at least 5 percent by binder weight of a compound that (i) is not a crystalline solid at room temperature, (ii) has at least two groups reactive with the crosslinker, (iii) has two to six ester groups, and (iv) comprises 10 to 48 carbon atoms. | 02-19-2009 |
| 20090053410 | COMPACT PAINTING PROCESS - A method of painting a substrate coated with an electrocoat, wherein the electrocoat includes an average surface roughness equal to or greater than 3 microns, includes applying a two-component sealer onto the electrocoat to form a film having a thickness of from 5 microns to 20 microns. The two-component sealer is partially cured by application of heat to a gel content of from 10 to 50 wt. %. Thereafter, a topcoat, typically including a basecoat and a clearcoat, is applied onto the two-component sealer. Both the two-component sealer and the topcoat are completely cured by application of heat. | 02-26-2009 |
| 20090162646 | COATING COMPOSITION FOR ACHIEVING EXCELLENT MVSS ADHESION - A coating composition comprises a crosslinkable carbamate-functional resin and an aminoplast. The aminoplast comprises the reaction product of an aldehyde and a melamine. The aminoplast has a content of imino groups of less than or equal to about 10%, a content of alkylol groups of at least about 7%, and a remainder of groups being alkoxyalkyl groups, all based on a total number of reactive sites present in the melamine prior to reaction. A coating system includes a clear coat layer that comprises the reaction product of the crosslinkable carbamate-functional resin and the aminoplast. Threshold adhesion strength, in accordance with MVSS standards, can be achieved between glass and the coating system when the crosslinkable carbamate-functional resin and the specific aminoplast set forth above are reacted to form the clear coat layer, while minimizing problems associated with high viscosity of aminoplasts having a high content of imino groups of greater than 10%. | 06-25-2009 |
| 20090258252 | COATINGS AND METHODS FOR IMPROVED ADHESION TO PLASTIC - Compositions and methods are provided that increase adhesion of a primer, such as an adhesion promoter, to a plastic substrate and/or increase adhesion of a topcoat to the primer. Chemical properties at the interface of the substrate and the adhesion promoter coating and/or chemical properties at the interface of the adhesion promoter coating and topcoat are modified in order to improve adhesion. | 10-15-2009 |
| 20100022712 | Coating Composition and Cured Film Formed Therefrom - A coating composition comprises a first copolymer and a second copolymer. The first copolymer has at least one linear polymer strand having a weight average molecular weight of at least 1,500 Daltons and functionality X with an equivalent weight of no more than 500. The second copolymer has at least one linear polymer strand having a weight average molecular weight of at least 1,500 Daltons and functionality X′ with an equivalent weight of no more than 1,500. The coating composition is free of gloss flattening agents, yet still produces a cured film having a low gloss of less than 70 gloss units at an angle of incidence of 60°, as measured according to ASTM D 2457. | 01-28-2010 |
| 20100152371 | METHOD FOR MAKING CHLORINATED POLYOLEFIN SOLUTIONS AND COATINGS - In method of making an organic solution of a chlorinated polyolefin that produces a storage-stable solution, a chlorinated polyolefin resin is dissolved in a hydrocarbon solvent that is predominantly aliphatic hydrocarbon, aromatic hydrocarbons other than toluene and xylene, or mixtures of these at a temperature of from 118 to 125° C., particularly at 120 to 122° C., held at the temperature for an adequate time for complete dissolution, particularly for at least about ninety minutes, then cooled and a cosolvent is added at a temperature below the boiling point of the cosolvent but at a temperature at which the chlorinated polyolefin solution is still clear or has little haziness, particularly at about 50 to 75° C. The solution may then be cooled, if needed, to a storage or use temperature. The solution has from about 60 to about 90 percent by weight of the mixture of the hydrocarbon solvent and cosolvent and from about 10 to about 40 percent by weight of chlorinated polyolefin resin. The solution has 0.1 to 10 wt % of the cosolvent. The solution can be used to prepare coatings, primers, inks, and adhesives, particularly for plastic substrates such as thermoplastic polyolefin. | 06-17-2010 |

| 20100183882 | Coating System For Achieving Excellent MVSS Adhesion - A coating system includes a clear coat layer and a sealant. The clear coat layer is formed from a clear coat composition that comprises a crosslinkable carbamate-functional resin and an aminoplast. Optionally, the coating system further includes a sub-clear coat layer that is formed from a sub-clear coat composition. The sealant is bonded to the clear coat layer opposite the sub-clear coat layer. Optionally, the coating system further includes a tie coat layer that is formed from a tie coat composition and that is disposed between the sealant and the clear coat layer. An adhesion promoter is present in the clear coat composition in an amount of less than or equal to about 3% by weight based on the total weight of resin solids of the clear coat composition. Further, the adhesion promoter is present in at least one of the sub-clear coat composition and the tie coat composition in an amount sufficient to increase adhesion between the clear coat layer and the sealant. | 07-22-2010 |
| 20100285308 | Composite Articles Having Excellent Adhesion Strength And Methods Of Forming The Same - A composite article generally comprises a substantially transparent outermost layer, a tie-layer, and a backing layer. The composite article can also include a substrate layer. The tie-layer imparts excellent adhesion strength between the substantially transparent outermost layer and the backing layer. The outermost layer is formed from a coating composition, e.g. a clearcoat paint composition, and can optionally be tinted. The tie-layer is formed from an adhesion promoting composition comprising a halogenated polyolefin, such as chlorinated polyolefin (CPO), and optionally, a solvent, such as an organic solvent. The backing layer is formed from a metal composition, such as chrome. If employed, the substrate layer is typically formed from a plastic, such as acrylonitrile butadiene styrene. The composite articles of the present invention may be used for various applications, such as for automobile parts and trim. The composite article can have an imparted aesthetic effect, such as being pewter in color. | 11-11-2010 |
