Abstract : This patent application discloses coating compositions and more specifically corrosion-resisting coating compositions which can be applied by various methods directly onto surfaces and particularly metal surfaces and/or polymeric or plastic substrates without the need for an undercoat. This coating is capable of being applied to various substrates as a single top coat having high-gloss, good adhesion and a high degree of flexibility. The corrosion inhibiting coating composition comprises an epoxide resin and a corrosion inhibiting pigment system consisting essentially of critical amounts of zinc phosphate, zinc molybdate and at least one zinc salt of a benzoic acid.
