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.
Chemfilm meets the MIL-DTL-5541 specification.
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.
