The present invention is directed to an electrodepositable coating composition comprising an electrodepositable binder comprising an ionic salt group-containing film-forming polymer comprising active hydrogen functional groups, and a blocked polyisocyanate curing agent; a solubilized bismuth catalyst; and a guanidine; wherein the electrodepositable coating composition has a weight ratio of bismuth metal from the solubilized bismuth catalyst to guanidine of from 1.00:0.071 to 1.0:2.1 and/or a molar ratio of bismuth metal to guanidine of from 1.0:0.25 to 1.0:3.0. Also disclosed are methods of treating electrodepositable coating compositions, methods for making electrodepositable coating compositions, systems for coating a metal substrate, coatings, coated substrates, and methods of coating a substrate.

Phosphate resistant electrodepositable coating compositions

Electrodepositable coating compositions containing 1,1-di-activated vinyl compounds are described. The coating compositions produce cured coating layers that exhibit resistance to cratering. The coating compositions can be used in electrodepositable coating composition formulations.
