<p>TITLE Coating Composition of An acrylic Polymer Having Amino Ester Groups And a Glycidyl Acrylic Polymer A coating composition which cures at ambient temperatures of 20-80% by weight of a binder and 80-20% by weight of a solvent for the binder, the binder contains about: A. 60-80% by weight, based on the weight of the binder, of an acrylic polymer of polymerized monomers of methyl methacrylate and an alkyl methacrylate, an alkyl acrylate or mixtures thereof, each having 2-12 carbon atoms in the alkyl group and the polymer has pendent amino ester or hydroxy amino ester groups; B. 20-40% by weight, based on the weight of the binder, of a glycidyl acrylic crosslinking polymer of polymerized monomers of glycidyl methacrylate or glycidyl acrylate and an alkyl methacrylate, alkyl acrylate or mixtures thereof, each having 2-12 carbon atoms in the alkyl group. The composition is useful as an exterior finish for automobiles and trucks and for repairing finishes of automobiles and trucks.</p> |
