ABSTRACT:
Low temperature curing aqueous coatings are provided by combining a water soluble bisphenol polyol with a branched copolymer of an unsaturated epoxy ester with monoethylenic monomers including about 3% to about 20% carboxyl-functional monomer, based on the weight of the copolymer, so that the copolymer can be dispersed in water with the aid of a volatile base. The solids content is increased or the viscosity is lowered, the curing temperature is reduced, and the corrosion resistance is enhanced by the presence of the bisphenol polyol.
