Abstract: The invention pertains to aqueous dispersed, crosslinked microgel polymers useful as a polymeric binder in protective coatings. The microgel polymeric binder comprises epoxy-acrylic graft copolymer dispersed into water, emulsion copolymerized monoethylenically unsaturated monomer, and emulsion copolymerized divinyl benzene adapted to crosslink in the emulsion copolymerization step with the monoethylenic monomers to produce the crosslinked microgel polymer particles. The microgel polymer is particularly useful as binder for can coatings adapted to be heat cured to form a protective film.

Abstract: A protective paint coating containing a polymeric binder having both hydrophobic and hydrophilic moieties in the polymeric structure comprises an acrylic-graft terpolymer. The terpolymer comprises aliphatic-modified glycidyl acrylate and epoxy resin coreacted with diphenol to form the terpolymer. Ethylenically unsaturated monomers, including carboxyl monomers, are in-situ copolymerized in the presence of the terpolymer to produce the acrylic-graft terpolymer. The aliphatic-modified glycidyl acrylate component of the terpolymer comprise the reaction product of a glycidyl acrylate and a branched aliphatic ethylenic monomer having a branched chain of 2 to 20 carbon atoms. The branched aliphatic chain and the carboxyl functionality provide the self-contained wetting agent properties to the polymeric binder structure.
