High Purity Zinc Phosphate (High Content Type)
PRODUCT APPLICATION
zinc phosphate, as a new generation of antirust pigment，is a new type of harmless white antirust pigment withexcellent performace in rust prevention and ideal application effect. It is the best subtitute of conventional antrustpigments containing heavy metals such as lead and chrome. lt mainly used in various coating materials for preparation of waterproof, acid-resistant or corrosion preventive coating materials such as phenolic paint, epoxypaint, acrylic paint, paste paint and water-soluble resin paint in the fields of shipbuilding,automobile, industrialmachinery, light metal, household appliances and metal containers for foods.
The new product High purity zinc phosphate is similar to PZ20.

Product performance & application
►Zinc phosphate in ferric ions have strong ability of condensation.
►The root of zinc phosphate ions and iron anodes reaction, can form to iron phosphate as the main body of the strong protective film, this dense purification membrane insoluble in water, high hardness, good adhesion shows excellent anti-corrosive properties. Because of zinc phosphate has excellent activity, gene with a lot of metal ions can transamination complex, therefore, has the good rustproof effect.
►Zinc phosphate is mainly used as the base material of various coatings such as aldol, phenolic, epoxy resin, etc., to prepare various water-resistant, acid-resistant, and anti-corrosion coatings, such as epoxy paint, acrylic paint, high-build paint and water-soluble resin paint, etc. . It is widely used in anti-corrosion paints for ships, automobiles, industrial machinery, light metals, household appliances and metal containers for food. In addition, it is also used in the production of anti-corrosion coatings and water-soluble coatings, and used for phosphating treatment of steel. And used as a flame retardant for chlorinated rubber and synthetic polymer materials.
► Product performance standards: China HG_T4824-2015 standard.
