Zinc phosphate coating agent
It is a chemical agent for improving the paint adhesion and corrosion resistance of steel products.
Zinc phosphate coating agents are used for surface treatment to enhance the adhesion and durability of coatings on steel products. The zinc phosphate coating is a dark gray film primarily composed of two types of crystals: hopeite and phosphophyllite. The industrial purpose of treating zinc phosphate coatings is to prevent rust on metal products and to make it difficult for the paint film to peel off as a primer. Zinc phosphate coatings are chemically very stable and are excellent as a primer. While iron phosphate coatings also exist as phosphate coatings, the corrosion resistance of zinc phosphate coatings is superior as a primer. *For more details, please refer to the related link page or feel free to contact us.*
