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 an aliphatic ethylenic monomer having a chain of 2 to 20 carbon atoms. The aliphatic chain and the carboxyl functionality provide the self-contained wetting agent properties to the polymeric binder structure.
