Abstract
Water-dilutable paint binders for the formulation of ecological stoving paints containing only minor quantities of organic solvents are described. The binders are partial condensation products of (A) a polycondensation, polymerization, or polyaddition resin as the film-forming polycarboxy compound (PC-component), and (B) an epoxy resin amine adduct (PH-component) carrying hydroxy groups and being water-insoluble under normal processing conditions. The products afford improved corrosion resistance and are particularly suited for the formulation of primers, intercoats (primer surfacers), and single coat paints.
