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 intro
ZPA is a kind of modified zinc phosphate. On the basis of zinc orthophosphate, synergistic anti-rust materials and modifiers are added for surface modification treatment, which improves the solubility of zinc phosphate, strengthens the ability of anti-rust organization, and makes up for The insufficiency of zinc phosphate's anti-rust ability in the early stage of paint coating and the problem of effective delay, improve the anti-rust and anti-corrosion ability, and can be better applied to water-based and oil-based anti-corrosion coatings. This modifier is also a non-toxic and low-heavy metal environmental protection material, and it is a white non-toxic and pollution-free anti-rust pigment suitable for coating systems.

Product performance & application
►As epoxy zinc phosphate paint, it is suitable for rust prevention in ports, docks, heavy machinery, mining machinery, grain machinery, power machinery, chemical equipment, water conservancy projects and other steel structures, as well as steel structures above the waterline of ships. Use of primer. ►Zinc-based phosphating solution; mainly used in the process section of steel surface anti-rust treatment. Principle: A liquid prepared with zinc phosphate, phosphoric acid and surfactant. After contact with steel, it can effectively dissolve iron oxides and release iron ions, forming a dense complex protective film on the surface of the steel. ►Zinc phosphate does not contain lead, chromium and other metals, and is non-toxic and non-polluting. It has no irritation effect on the skin, good thermal stability, strong anti-rust ability, less dosage in paint, and low cost. Because the pigment is white, it can be matched according to needs, which can simplify the painting process and painting process. ►Multi-purpose spray primer, low temperature curing, short recoating time, not limited by recoating time, can be overcoated by various high-performance topcoats, used for protection of sandblasted steel, whether wet sandblasting or dry sandblasting . ► Product performance standards: China HG_T4824-2015 standard.
Transport & storage
In order to avoid weathering, it should be stored in a dry place while avoiding drastic changes in temperature. Products that have been packaged should be closed to prevent moisture absorption and pollution
