Abstract: A powder coating composition that includes at least about 9% by weight, based on total vehicle weight, of a branched carboxylic acid-functional polyester having a number average molecular weight of from about 425 to about 1050 and at least one vehicle component reactive with carboxylic acid groups comprising an epoxy-functional material, produces a matte, textured coating.
Abstract: The invention provides a coating composition for use with metallic substrates that provides a unique balance of required properties. In particular, the coating composition of the invention simultaneously provides desirable levels of adhesion to metal, sandability without the production of harmful dust, corrosion resistance, and recoatability. The coating composition of the invention comprises a polyurethane or epoxy/amine film-forming component, and a corrosion protection component consisting of aluminum selected from the group consisting of nonleafing aluminum pigments, the corrosion protection component being present in the composition in an amount effective to prevent corrosion of the substrate. A cured film of the coating applied to a steel substrate has a pass rating after 480 hours in salt spray per ASTM B117.
