THERMOSETTING, HIGH-SOLID COATING COMPOSITION AND METHOD OF FORMING TOPCOATING BY USING THE SAME

摘要

A thermosetting, high-solid coating composition characterized by comprising: (A) a carboxylated compound, (B) a polyepoxide, and (C) a copolymer prepared by polymerizing a monomer component comprising (a) 30 to 50 % by weight of vinyltrimethoxysilane and/or vinyltriethoxysilane, (b) 5 to 15 % by weight of N-methylol(meth)acrylamide alkyl ether, and (c) 35 to 65 % by weight of other polymerizable unsaturated monomer. The composition has significant effects, that is, can yield a coating excellent in acid resistance and scuff resistance and also excellent in storage stability and recoatability.
