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

The present invention is directed to an electrodepositable coating composition comprising an acrylic polymer comprising greater than 60% by weight of constitutional units comprising the residue of a hydroxyl-functional (meth)acrylate monomer and/or a hydroxyl-functional (meth)acrylamide monomer, based on the total weight of the acrylic polymer; and an ionic salt group-containing film-forming polymer different from the acrylic polymer. Also disclosed are coatings, coated substrates, and methods of coating a substrate.

Electrodepositable coating compositions

The present invention is directed towards an electrodepositable coating composition comprising a cationic electrodepositable binder; a phyllosilicate pigment; and a dispersing agent.
