ABSTRACT:
An electrodepositable composition is provided comprising (a) an active hydrogen-containing, cationic salt group-containing resin electrodepositable on a cathode; (b) a capped polyisocyanate curing agent; and (c) a diorganotin dicarboxylate; wherein the dicarboxylate is at least one long chain carboxylate having from 14 to 22 carbon atoms and the diorganotin dicarboxylate is present in the electrodepositable composition in an amount of at least 0.01 percent by weight tin based on weight of total solids of the electrodepositable composition. The composition provides improved storage stability without precipitation of dibutyltin oxide, and when electrodeposited over conductive substrates, there is no loss of cure response and appearance properties.
