Zinc Phosphate

What is a Zinc Phosphate Coating?

Zinc Phosphate coatings are often used on steel parts to provide corrosion protection, lubricity, or as a pretreatment for additional coatings. The process converts the metal surface into a nonmetallic, polycrystalline coating, which has a black matte appearance.

AFT offers both rack and bulk barrel-plating processes, both exceeding the American Petroleum Institute specifications for coating weight, and they maintain a fine crystal structure that can hold oils and withstand handling.

AFT has selected chemistry from MacDermid (Keykote 36 & 40), one of the most dependable and respected products and suppliers in the plating industry.
