A&P here. Zinc chromate is used as a primer on aluminum surfaces as a conversion process to inhibit corrosion. Since nearly all modern aircraft skins and structures are made from aluminum, this compound and its derivatives are the most common primers seen in aircraft manufacturing.
Chromate conversion coating is a type of conversion coating used to passivate steel, aluminum, zinc, cadmium, copper, silver, magnesium, and tin alloys.hromate conversion coatings on an aluminum substrate are known by the following terms: chemical film, yellow iridite, and the brand names Iridite and Alodine. It is also commonly used on aluminum alloy parts in the aircraft industry. Iridite NCP is a non-chromium type of conversion coating for aluminum substrates.
