Zinc phosphate coatings are used to improve corrosion resistance.  The zinc phosphate coating process converts the metal surface to which it is applied into a nonmetallic, polycrystalline coating that contains iron, manganese, nickel and zinc phosphates.  This process can be used to treat metals individually or in mixed production.

Why Zinc Phosphate Coating?
In addition to corrosion resistance, the zinc phosphate coating process can improve the appearance of finished goods through the creation of a uniform gray or black appearance.  The process is also a cost-effective alternative to plating or painting, particularly on hidden metal parts.
