Phosphate Treatment

   Phosphate is a metal conversion coating process. There are many kinds of such as Zinc phosphate, Zinc calcium phosphate, manganese phosphate. We apply phosphate coating on many applications such as Anti-corrosion, Based for organic coating, Anti-seizer for cold forming, Wear resistance. After surface cleaning by suitable technique, metal will be reacted by Phosphate chemical and generate an even crystal of the phosphate compound. Aluminum surface can also be coated by Non-chrome or Tri-valent chrome chemical.
