US Classification:

4273855, 427386, 427387, 525108, 525110, 525111, 525117, 525123, 525124, 525125, 525131, 525133, 525142, 525155, 525161

Abstract:

The present invention provides a curable coating composition that includes a film-forming polymer, a polymeric additive having at least one bound surface protecting group, and a crosslinker that is reactive with the film-forming polymer. The polymeric additive is substantially free of groups reactive with the crosslinker and has comonomer units with aryl groups, alkyl groups having, on average, four or more carbon atoms, or combinations of the aryl and alkyl groups. When the coating composition is cured to form a cured coating layer, the concentration of the polymeric additive in the upper about 50% of the cured coating layer thickness is at least about 10% higher than the concentration of the polymeric additive in the rest of the cured coating layer.

International Classification:

B05D 302

US Classification:

427180, 4273855

Abstract:

The invention provides a method of obtaining improvements in the appearance of articles having both vertically and horizontally orientated surfaces and a coating composition for use in said method. The coating composition of the invention has a film-forming component (a) and a rheology control agent (b) having substantially colorless, substantially inorganic microparticles (i) and a compound (ii) comprising the reaction product of an amine and an isocyanate. A particularly preferred method of the invention requires applying the coating composition of the invention to an article having at least one horizontally orientated surface and at least one vertically orientated surface so as to provide a coated horizontally orientated surface and a coated vertically orientated surface, wherein the coated vertically orientated surface has improved sag resistance, most preferably having a sag resistance of at least 1. 2 mils. The coated surfaces are then cured to provide a cured horizontally orientated film having an improved surface appearance, most preferably a surface appearance having a DOI of at least 70.

US Classification:

524155, 4284231, 524590, 524591, 524839, 524840

Abstract:

A clearcoat composition and method reduce the ability of rain to bead on a film of the clearcoat. The clearcoat includes a resin, a cross-linking agent reactive with the resin, and a water-soluble surfactant. Upon exposure of the film to the rain, the surfactant reduces the ability of the rain to bead on the film and certain properties, such as resistance to etch from acid rain, are improved.

International Classification:

C07D 251/30

US Classification:

524101, 524492, 252403, 544192, 544218

Abstract:

A curable coating composition includes a plasticizing component. The plasticizing component includes an isocyanurate core and at least one low surface tension group pending from the isocyanurate core. The low surface tension group may be a) a fatty chain includes at least 6 carbon atoms, b) a silicon-containing group having at least 1 silicon atom, c) a fluorocarbon, and combinations thereof. The low surface tension group may have cross-linkable functional groups pending therefrom. In addition to the plasticizing component, the curable coating composition further includes a resin component and a crosslinking agent that is reactive with the resin component. The curable coating composition including the plasticizing component is capable of forming a cured film that has resistance to both cracking and etching that, to date, has not been achieved with known plasticizing components.

International Classification:

C09B 67/00

US Classification:

524502, 524556

Abstract:

A coating composition is used to form a clearcoat layer of a film system including a basecoat layer and the clearcoat layer. The coating composition includes a carbamate functional polymer, a cross-linking agent reactive with the carbamate functional polymer, and an acid functional polymer substantially non-reactive with the carbamate functional polymer and the cross-linking agent. The acid functional polymer has an acid value of at least 50 mg KOH/g and contributes to an increased resistance to acid etch of the clearcoat layer. The acid functional polymer also contributes to an increased intercoat adhesion of the basecoat layer and the clearcoat layer thereby decreasing a possibility of separation/delamination of the basecoat layer and the clearcoat layer.

US Classification:

436005000

Abstract:

The present invention provides a test method for simulating outdoor exposure conditions for testing a coated substrate to evaluate environmental etching of paint caused by acid rain. The test method requires that the test substrate have an acid solution having a pH of less than 6.0 applied thereto by spray or in atomized droplets. The substrate is held in a substantially horizontal position of less than 15 to the horizontal and exposed to heat of above a black panel temperature of 30 C. and light during testing. The light source must emit light in the spectral distribution of at least visible and ultraviolet light, including the spectral distribution of sunlight. Following exposure to testing the substrate is evaluated for environmental etch.
