Summary: | The present disclosure relates to an improved electrocoating coating composition wherein the improvement is the addition of a non-water reducible anticrater agent. The non-water reducible anticrater agent is a polyesterurethane that is the reaction product of an aliphatic carboxylic acid anhydride, a monofunctional epoxy compound, a monofunctional alcohol and a diisocyanate and/or a polyisocyanate. The improved electrocoating composition provides cured coatings that have fewer craters and have a smooth surface when compared to coatings utilizing other anticrater additives. |
