Aluminum Conversion Coatings

IRIDITE COATING

Iridite chromate based coating is a passivation treatment designed specifically for aluminum alloys. Keystone Iridite coating for aluminum provides a highly corrosion resistant conversion coating ideally suited to be painted or left as a stand alone corrosion resistant barrier.

Keystone Iridite provides both high adhesion values for paints and powder coatings as well as excellent corrosion resistance in its own right. This means that even unpainted areas of aluminum are protected against corrosion. Keystone Iridite is the reliable and cost effective chromate based pretreatment for aluminum.
