Abstract
Water-dilutable coating binder combinations which can be deposited cathodically, and based on epoxy resin-amine adducts, acrylate copolymers and crosslinking components are described. The binders are particularly suitable for formulation of water-dilutable primers and one-coat paints when deposited cathodically are described. In 3 to 30% by weight, based on the solids, of a basic epoxy resin-amine adduct (A) which is free from epoxide groups, 70 to 97% by weight of a monomer mixture (B), which consists of esters of (meth)acrylic acid which contain secondary or tertiary amino groups, of monoesters of (meth)acrylic acid with diols, of (meth)acrylic acid alkyl esters and if appropriate of aromatic vinyl monomers, is polymerized. Components (A) and (B) comprise at least 5% by weight, preferably 10 to 20% by weight, of identical aliphatic radicals having 7 to 18 carbon atoms. The baked films based on these products have a high degree of gloss and an excellent UV, washing agent, and corrosion resistance.
