Chemical film coating, also referred to as Chem Film applies a chromate conversion coating on aluminum, producing a finish which protects from corrosion, conducts electricity and allows for good paint adhesion.

Class 1A Chemical Conversion Coatings are intended to provide corrosion prevention when left unpainted and to improve adhesion of paint finish systems to aluminum and aluminum alloys.

Class 3 Chemical Coatings are intended as a corrosion preventive film for electrical and electronic applications where low resistance contacts are required.

Miramar Metal Processing also provides Rohs Compliant chromate conversion coating – please refer to TCP-HF.
