Chromate Conversion Coating

Chromate conversion coatings on aluminium are also known as yellow Bonderite, Irideite, and Alodine, or Chem Film. They are used for everyday aluminum components, hardware, automotive wheels, heat sinks and aerospace applications. Chromate conversion coating is applied by dipping, spraying, or brushing, and the coating thickness doesn;t change the dimensions of the coated part. If applied to a surface before the partner, it can improve the adhesion of both primer and paint.
