COATING COMPOSITIONS OF ACRYLIC-EPOXY ESTER GRAFT COPOLYMERS UTILIZING AZIRIDINYL ALKYL ACRYLATE OR METHACRYLATE IN THE COPOLYMER

摘要

The novel coating composition consists essentially of a graft copolymer dissolved in an organic solvent wherein the backbone of the graft copolymer is of polymerized constituents of an alkyl acrylate, an alkyl methacrylate in which the alkyl groups have one to three carbon atoms or styrene and also can contain acrylic constituents having adhesion promoting groups; the copolymer has graft into the backbone through a coupling unit of an aziridinyl acrylate or an aziridinyl methacrylate a side chain of an epoxy ester. The composition forms a high quality coating and is useful as a primer or as sealer composition in the manufacture of automobiles and trucks.
