Summary:An electrocoat coating composition contaminated with phosphate ions is treated by adding zirconium silicate to the coating composition. Aqueous electrocoat coating compositions including (1) a bismuth compound and that is free of tin compounds and free of bismuth hydroxide or (2) having a catalyst consisting essentially of a member selected from the group consisting of bismuth compounds and mixtures of these also include zirconium silicate.
