Abstract

Binder combinations for the formulation of cathodic paints comprising blends of epoxy resins as follows: (A) 40 to 80% by weight of reaction products of epoxy acrylates with basic monoisocyanates; (B) 5 to 30% by weight of reaction products of epoxy amine adducts with unsaturated monoisocyanates, and (C) an epoxy resin modified with a semi-ester of a dicarboxylic acid anhydride and an N-hydroxyalkyloxazolidin and an amine, rendered water soluble through neutralization of the basic groups. The binder combinations as defined have enhanced throwing power and improved stability of the paint tank.
