HIGH-SOLID COATING COMPOSITION AND METHOD OF TOPCOATING WITH THE SAME

摘要

A high-solid thermosetting coating composition characterized by containing: (A) a copolymer prepared by polymerizing a monomer component composed of (a) 30 to 50 % by weight of vinyltrimethoxysilane and/or vinyltriethoxysilane, (b) 5 to 15 % by weight of an N-methylol(meth)acrylamide alkyl ether and (c) 35 to 65 % by weight of another polymerizable unsaturated monomer, (B) a hydroxylated resin having a hydroxyl value in the range of 10 to 200 mgKOH/g, and (C) a curing catalyst, and a method of topcoating with the same. The composition has remarkable effects of being capable of forming coating films excellent in acid and scuff resistances and being excellent in storability and recoatability.
