Overview
Chemical conversion coatings sometimes referred to as chromate conversion, chem film, Iridite or Alodine refer to a process of applying a thin barrier coating on the substrate to passivate aluminum alloys to slow the formation of corrosion. It is gelatinous film that has self-healing properties and improves paint adhesion on aluminum alloys and die castings. It can also be applied to zinc die castings.
