When Bonding & Corrosion Is Critical

• MIL-C-5541 Class 3 Color gold

Quality Coatings of Spokane Washington is proud to offer Chromate Conversion, also known as Gold Chem Film. Quality Coatings chromate conversion coating leaves no measurable build-up on the part and provides excellent corrosion resistance. In many paint or adhesive applications, chromate is used as a base for superior bonding. The coating is conductive and offered in yellow iridescent.

Applying 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.

Chromate treatments (sometimes called chemical film) 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-C 5541 for bare (unpainted) corrosion resistance
• Low contact resistance: meets electrical conductivity requirements on aluminum substrates, per MIL-C 5541 class 3
• Meets paint adhesion requirements per MIL-C 5541
