High-Quality White Powder Anti-Rust Pigment - Trusted Zinc Phosphate Tetrahydrate Factory

Product intro

Zinc phosphate primer is non-toxic and non-hazardous, which is used to replace red lead, zinc chromium yellow and other traditional heavy metal anticorrosive and antirust pigments. Its antirust ability is better than traditional antirust pigments, and its spatial structure can make it better impact resistance as a primer or middle layer paint. Especially after modification of zinc phosphate, because phosphate ions and zinc ions are easier to ionize, the rust prevention effect is basically the same as zinc chromium yellow. Among them, zinc phosphate epoxy powder has a better effect, which can prolong the life of the paint body and make the rust prevention effect more obvious. Zinc-rich primer and epoxy zinc phosphate middle layer paint are widely used in the construction of open-air heavy anticorrosion and open-air stadiums

Product performance & application

►Because the pigment is white, it can be matched according to needs, which can simplify the painting process and painting process. Zinc phosphate does not contain metals such as lead and chromium, 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. ►Zinc phosphate, colorless orthorhombic crystal or white microcrystalline powder, corrosive and deliquescent. It is soluble in mineral acid, ammonia water, ammonium salt solution; insoluble in ethanol; almost insoluble in water, and its solubility in water decreases as the temperature rises. When heated to 100℃, it loses 2 crystal water and becomes anhydrous. It is used as a base material for various coatings such as aldol, phenolic, epoxy resin, chlorinated rubber, and a flame retardant for synthetic polymer materials. It is also used to produce water-soluble coatings and non-toxic anti-rust pigments. ► 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
