摘要： A water reducible polyurethane resin for use in coating compositions is provided with humidity resistance at relatively low cost by employing a urethane prepolymer which is the reaction product of (i) a polyisocyanate, (ii) a polyhydroxy compound which is the reaction product of an organic acid and an epoxy compound, at least one of which includes a hydrocarbon group of at least six carbon atoms, and (iii) a monomer having an anionic group and functionality reactive with isocyanate. Preferred embodiments employ C.sub.36 dimer diacid and the propylene oxide ester of neodecanoic acid to make the polyhydroxy compound.

摘要： A flexible, aminoplast-curable film-forming composition can serve as a transparent coating composition for a multi-component composite coating composition having the transparent coating on a pigmented or colored base coat. The film-forming composition comprises at least two polymeric components. One is a polyether polymer containing a plurality of terminal and/or pendant carbamate groups of the structure: ##STR1## Another is at least one additional carbamate functional polymer along with urethane oligomer or is a polyurethane polyol. The former include carbamate functional polyester, acrylic polymer, and polyurethane, where each contains a plurality of terminal and/or pendant carbamate groups of the Structure I depicted above. Also the urethane oligomers has a plurality of carbamate groups of Structure I that are pendant and/or terminal. The latter polyurethane polyol has a plurality of pendant and/or terminal hydroxyl groups and optionally can be used with the urethane polyol and/or any of the aforementioned carbamate functional polymers. Optionally an additional polymer that is present is an acrylic polymer containing a plurality of amide groups with or without a plurality of terminal and/or pendant carbamate groups of Structure I. Also with the presence of the amide functional acrylic polymer, silica can be employed. Additionally for crosslinking the film-forming composition contains an aminoplast crosslinking agent.

摘要： A waterborne coating composition having a crosslinking agent and a dispersion of polymeric microparticles in an aqueous medium wherein the microparticles are prepared by first forming a mixture in the aqueous medium of ethylenically unsaturated monomers and a substantially hydrophobic, saturated fatty acid-containing polyester. The amount of fatty acid used to prepare the polyester ranges from about 20 to 80 weight percent of the total weight of the fatty acid-containing polyester. The fatty acid-containing polyester contains functional groups which are capable of reacting with the crosslinking agent. The mixture is particularized into microparticles by high stress techniques, followed by polymerization of polymerizable species within the microparticles to produce the polymeric microparticles. The amount of the fatty acid-containing polyester in the dispersion is at least 10 and up to 70 weight percent based on weight of the ethylenically unsaturated monomers and fatty acid-containing polyester. The amount of the polymeric microparticles in the coating composition is from 20 to 80 weight percent based on total weight of resin solids in the coating composition.

摘要： Flexible, aminoplast-curable film-forming compositions and multi-component composite coating compositions comprising at least one pigmented or colored base coat and at least one transparent clear coat are disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a clear coat to the base coat. Both the colored base coat and the clear coat are flexible, curable film-forming compositions having an aminoplast crosslinking agent, and the base coat and optionally the clear coat has carbamate functional polymers. The flexible, multi-component composite coating compositions provide improved durability, water spotting resistance, and/or acid etch resistance, making the composite coatings particularly useful for plastic automotive parts.
