ABSTRACT:
The present invention provides a resin which is a mixture of a) the product of a diol and one or more diepoxides and b) an A-B-A block copolymer wherein A represents blocks of an epoxy/diol copolymer which is the reaction product of a diol and a diepoxide, and B represents blocks of an epoxy-capped, carboxyl-terminated polybutadiene or polybutadiene/acrylonitrile copolymer.
Amine resins, produced by reaction of this resin with an amine are useful as the principal resin in electrocoating formulations which produce deposited films having excellent corrosion resistance and improved impact and chip resistance.
