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