Quality Coatings of Spokane Washington is proud to offer chemical conversion coatings in both TYPE I and TYPE II. Quality Coatings chemical conversion coating leaves no measurable build-up on the part and provides excellent corrosion resistance. In many paint or adhesive applications, chem film is used as a base for superior bonding. The coating is conductive and offered in yellow iridescent (TYPE I) and clear (TYPE II).
Applying the chromate solution to clean aluminum produces a thin, gel-like film, which is an integral part of the metal itself, but converted to a non-metallic form. Chem film treatments produce effective paint bonds through molecular adhesions with the film being bound to the metal, in turn offering the same type of adhesion to the organic coating. The film lengthens the life of the paint, forming an effective barrier against corrosive attack through pores or scratches in the paint.
Meets or exceeds MIL-DTL-5541F for bare (unpainted) corrosion resistance.
Low contact resistance: meets electrical conductivity requirements on aluminum substrates, per MIL-DTL-5541 Class 3 Meets paint adhesion requirements per MIL-DTL-5541F.
