Lincoln Chemical’s LincPlate chromate conversion coatings are formed by the reaction of water solutions consisting of chromic acid or chromium salts. Our conversion coatings can be applied to aluminum, zinc, cadmium, and magnesium with good atmospheric corrosion resistance. Chromate conversion coatings are widely used in protecting common household products, such as screws, hinges, and many hardware items with the yellow-brown appearance.
