Abstract
Abstract Paint coating material capable of cathodic deposition based on a vehicle mixture that has been made water-thinnable with acid and optionally customary additives, wherein said vehicle contains in combination (A) from 50 to 90% by weight of a polymer and/or polycondensate containing tertiary amino-groups and OH groups and having amine and hydroxy numbers of from 30 to 170 and 30 to 300 respectively; (B) from 5 to 40% by weight of a fully blocked polyisocyanate which is stable in the aqueous phase and becomes reactive again under the influence of heat, after dissociation of the blocking group; and (C) from 0 to 30% by weight of polymer and/or polycondensate containing primary and/or secondary OH- and/or amino-groups.
