Details
Zinc Phosphate Molecular Formula: Zn3(PO4)2 2H2O Zinc phosphate, as a new generation of antirust pigment, is a new type of nontoxic and harmless white antirust pigment with excellent performance in rust prevention and ideal application effect. It is the best substitute of conventional antirust pigments containing heavy metals such as lead and chrome. With powerful condensing property with ferric ions, Zinc Phosphate is able to form a durable protective film composed mainly of ferric phosphate through its radical ions reacting with iron anode. It is a highly dense pure film, insoluble in water, of high hardness, excellent adhesion and outstanding rust-preventing characteristics. The perfect rust prevention performance of Zinc Phosphate with many metals is resulted from its good activity in forming complex compounds with metallic ions. Zinc Phosphate will render coating materials excellent rust-preventing performance and good resistance to water. Therefore, it is widely used in various coating materials for preparation of waterproof, acid-resistant or corrosion preventive coating materials such as phenolic paint, epoxy paint, acrylic paint, paste paint and water-soluble resin paint in the fields of shipbuilding, automobile, industrial machinery, light metal, household appliances and metal containers for foods. The technical specifications are as follows in conformance to Standard Q/84XS01-2004.
