Abstract
A cationic finely divided polymeric microgel dispersed in an aqueous medium for use in cationic electrocoating compositions of an epoxy terminated polyepoxy hydroxy ether resin being end capped with a ketimine, a primary amine, secondary amine or mixtures thereof and amino siloxane to provide silanol groups and amino groups; the amino groups of the polymeric microgel being neutralized with an acid to form cationic groups for water dispersibility and the silanol groups being condensed with hydroxy groups of the resins and other silanol groups of the resin thereby forming a crosslinked microgel.
