(Chrome Phosphate Pre-Treatment)
Chem-Film is a chemical conversion process that prepares aluminum extrusions for field painting. Chem-Film coating is also referred to as Chemical Film Coating, Chromate Conversion, Iridite and Alodine. Chem-Film is a cleaning process and then a Chrome Phosphate Pre-Treatment. The process begins by cleaning the aluminum trim and then a protective coating is applied until primer and paint can be applied. Paint manufacturer should be consulted when choosing a primer.
The Chem-Film process protects aluminum from short-term corrosion and assures good paint adhesion. Chem-Film is not intended to be a final finish for any exposed portions of aluminum trim. Aluminum trim that has had a Chem-Film coating applied, typically has a "greenish" tinge to it before the primer has been applied.
