Zinc Phosphating

Zinc Phosphating produces a very consistent, fine-grained protective coating on a wide variety of steel alloys. Commonly used as a conversion coating, zinc phosphate coatings are used as a paint base for improved corrosion resistance and performance. Zinc Phosphating has a superior ability to hold rust-inhibiting oils. Zinc Phosphating offers excellent anti-corrosion and anti-galling characteristics. Coating weights are uniform and consistent.

Zinc Phosphating is commonly used as a final protective coating for storage or as a pretreatment prior to powder coating or other one-coat finishes. This particular phosphate coating is frequently used in military applications for equipment that will be exposed to severe environments. Delstar's Zinc Phosphating tank is 10'L x 6'W x 5'D.
