ZINC PHOSPHATE COATING

Zinc phosphate coatings typically serve as a base on steel for dry film lubricants,  metal flake coatings, or lubricating oils. They may also be used for dry lubrication to improve break-in or reduce galling. Commonly, zinc phosphate is applied for the automotive industry and in certain sectors of the appliance and electronics industries, as well as the armed services for equipment that could be exposed to severe environments. Many operations using electrocoating or powder coatings, particularly when a one-coat finish will be exposed to the weather, pretreat workpieces with zinc phosphate. Keystone Corporation’s Zinc Phosphate coating widely improves corrosion resistance and paint adhesion on steel and iron parts. Keystone's Zinc Phosphate coating is excellent at absorbing oil or wax. We have facilities for zinc phosphate coating both small and large parts in both rack and barrel.

ZINC PHOSPHATE COATING APPLICATIONS

Zinc Phosphate coatings are generally used to improve corrosion resistance. However, due to their porosity, Zinc Phosphate coatings require oil or other sealers to provide corrosion protection.

The following are common uses for zinc phosphate coating:

  • Provide a uniform base for paint adhesion
  • Good non-metallic crystalline coating for absorbing oil or wax
  • Protect parts from corrosion or wear
