Iron Kote Phosphatizer

Metal Treatment | Iron Kote™ 120 Series

One-Step Cleaner and Iron Phosphatizer. Iron Kote™ 120 is a liquid metal treatment that produces a crystalline iron phosphate coating on steel, cast iron, and zinc-coated alloys through either spray or immersion application. The result is excellent corrosion protection and exceptional paint adhesion compared to untreated metal — all from a single product. Designed specifically for industrial users who want to save time and process steps, Iron Kote 120 combines cleaning and phosphatizing into one efficient operation.
