PT-402 Acid Etching Primer, when properly reduced with PT-1045 Reducer, meets and exceeds MIL-C-8514C.
PT-402 is a polyvinyl butyral zinc chromate formulation that may be used to prime all plain or plated metallic
surfaces. Priming surfaces with PT-402 Acid Etching Primer prior to priming with epoxy primer MIL-PRF-
23377 or by itself will ensure maximum adhesion and protection of all bake or air-dry finish coats (including lacquer
finish coats). The finely ground emulsions of zinc chromate 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 8 hours.
Extreme humidity can affect the bonding of the coating.
