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.
Self-Etching Primer. An etching primer uses an acid to chemically clean and micro-etch the metal surface for a better mechanical bite to promote adhesion with the layer of high-build primer to follow while also providing a layer of corrosion resistance on the metal. Because it cures quickly, itâs the method of choice for collision shops.
