MIL-C-8514C is a polyvinyl butyral zinc chromate formulation that may be used to prime all plain or plated metallic surfaces. Priming surfaces with Acid Etching Primer will ensure maximum adhesion of all bake or air-dry finish coats (including lacquer finish coats). The finely ground emulsions of zinc phosphate pigments, resins and phosphoric acid hardeners are virtually non settling. Once applied, the Acid Etching Primer requires no sanding and has a pot life of 4~6 hours. Extreme humidity can affect the bonding of the coating.
