Abstract
Heat-curable surface-coating agents which, for example in their protonated form, can be used in cathodic electrocoating contain, as a binder, a mixture of (A) a polyadduct, polycondensate or other polymer which has an average molecular weight M.sub.n of from 500 to 10,000 and, per molecule, on average two or more OH and/or NH groups and (B) a reaction product of a polyisocyanate and an olefinically unsaturated amine which carries a secondary amino group and a methacrylamide or methacrylate group.
Claims8
A heat-curable surface-coating agent which contains, as a binder, a mixture of (A) from 50 to 95% by weight of a polyadduct, polycondensate or other polymer which has an average molecular weight M.sub.n of from 500 to 10,000 and, per molecule, on average two or more OH or NH groups or OH and NH groups and (B) from 5 to 50% by weight of a reaction product of a polyisocyanate and an olefinically unsaturated amine which carries a secondary amino group and a methacrylamide or methacrylate group.
