1 SCOPE.

This standard covers the basic requirements for a corrosion protective coating system which is derived from the application of an aqueous solution containing uniformly dispersed zinc platelets or flake, chromates and proprietary inorganic material. The coating is then top coated with an aqueous based sealer compound. The sealer may be unpigmented (clear) or pigmented with a color (black, blue, etc.). Parts top coated with clear sealer shall have a metallic gray appearance. Parts to be top coated with a color pigmented sealer shall be specified (Example, GM6173M black).
