Zinc phosphate is an inorganic compound. This white powder is widely used as a corrosion-resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment. It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor.
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 or dark grey appearance.
Central Kentucky Processing offers both rack and bulk barrel-plating processes, both exceeding the American Petroleum Institute specifications for coating weight, and a heavy zinc crystal structure that can hold oils and withstand handling.
While the specific method of application is determined by your project specifications, Zinc phosphate coating is adaptable to nearly any situation. One of the reasons zinc phosphate coating is so popular is its ability to be used across a wide variety of projects, industries, and applications! CKP applies dry-to-touch oil after processing.
