Overview
Chromate Conversion Coatings, sometimes called Chromate or Chem-Film, refers to applying a thin barrier coating on the substrate to passivate aluminum alloys to slow the formation of corrosion. The film improves paint adhesion on aluminum alloys and die castings. Chromate has no measurable thickness.
