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.
3. Zinc rich primers are used to protect steel surfaces from corrosion. Unlike regular paints or epoxies which resist corrosio. by forming an impermeable barrier between the metal and atmospheric moisture, zinc rich primers provide corrosion. protection by electrical means.ome types of zinc rich primers are used as a stand alone coating, but often they are topcoated with paint or epoxy (many. industrial coating specifications call for a zinc primer, epoxy intermediate coat and a urethane topcoat).
