ABSTRACT:
A non-chromate, corrosion-inhibiting coating composition for metal surfaces includes at least one inhibitor selected from the group consisting of phosphates, phosphosilicates, silicates, and mixtures thereof, at least one inhibitor selected from the group consisting of titanates, zinc salts, and mixtures thereof, and a carrier for these inhibitors, the carrier capable of placing the inhibitors in proximity with the metal surface. In a preferred embodiment, the coating composition further includes a borate such as boric acid, and a succinate. A preferred phosphate includes calcium dihydrogen phosphate, and sodium titanium oxide is a preferred titanate. The zinc salt can include zinc phosphate or zinc cyanamide.
