ABSTRACT:
A waterborne corrosion resistant primer composition is composed of a waterborne resin system; an optional curing agent; and a non-chromate containing corrosion inhibiting additive. The non-chromate corrosion inhibiting additive includes at least one of an anodic corrosion inhibitor, a cathodic corrosion inhibitor and a metal complexing agent. The metal complexing agent increases the solubility of at least one of the anodic and cathodic corrosion inhibitors.
