Zinc Phosphate is a nontoxic and harmless white antirust pigment which we export, supply and import for our esteemed clients. It is used in corrosion resisting primers, undercoats and in various coating materials for preparing waterproof, acid-resistant or corrosion preventive coating material such as phenolic paint, epoxy paint, acrylic paint, and paste paint. Zinc Phosphate is also used in making fertilizers and is known for its great compatibility, corrosion resistance, good brushing and excellent inter- coat adhesion.
