CHEM-FILM

Aluminum chromate conversion coatings (often referred to as chemical film, Alodine, Alocrom, or Iridite) are used where maximum protection from corrosion is required.

Typical uses include:

(1) As a primer to improve the adhesion of paints and adhesives, including the adhesives used to bond nut plates;

(2) As a corrosion inhibitor on small areas that will to be left unpainted;

(3) To preserve conductivity in electrical bond areas.
