Chromate conversion coatings (Chemfilm) are a varying group that can be done as a stand alone finish, used by itself, or as a secondary post finish treatment, used over a metal plating. Chemical Film on Aluminum, also called by proprietary names of Alodine or Irridite, is a thin, clear or yellow conversion coating used as a primer for paint, general protection to prevent aluminum from oxidizing, or used in conjunction with masking of an anodized finish for conductivity properties.
