Coating composition of a glycidyl acrylic polymer, an aminoester acrylic polymer and a polyester or a polyesterurethane

摘要

A coating composition which cures at ambient temperatures and contains a binder and a solvent for the binder, wherein the binder contains about: A. an acrylic polymer A having pending from the polymer backbone aminoester groups, hydroxy aminoester groups or hydroxyamine groups, B. an acrylic crosslinking polymer B of polymerized monomers of at least 3% by weight of a glycidyl constituent of glycidyl methacrylate or acrylate, and the remainder of the monomers are alkyl methacrylate an acrylate each having 1-12 carbon atoms in the alkyl group; C. a polyester or polyesterurethane polymer C having at least 2 pendant groups of the formula (* CHEMICAL STRUCTURE *) the composition is useful as an exterior finish for automobiles and trucks and for repairing finishes of automobiles and trucks.
