Zusammenfassung:	A corrosion-resistant coating which can be applied directly to a surface as a self-priming topcoat comprising an epoxy resin binder and a combination of pigments consisting essentially of an alkaline earth metal phosphosilicate, zinc salts of benzoic acids, and an alkaline earth metal phosphate such as zinc-barium phosphate. In addition, the coating contains up to about 35 parts by weight of a titanium dioxide pigment, up to about 3.0 parts by weight of an oil soluble surface active agent and up to about 50 parts by weight of at least one organic solvent.
