Property: Colorless crystal or white crystal. The appearance density: 0.8~1g/cm3. It is organic acid, ammonium water, ammonium solution soluble. It is water, alcohol insoluble. It has Deliquescence. Corrosive. It can be used as Alkyd, phenolic, epoxy paint base material. For the production of non-toxic anti-rust paint and water soluble paint. Also used as a chlorinated rubber, synthetic polymer materials, flame retardant.Zinc phosphate can replace Red lead, zinc yellow, and other traditional anti-rust paint Choromium. It can be used in Steel, shipbuilding, electrical appliances, equipment rust resisting. Zinc phosphate is a kind of white toxicity free anti-rust dyes. It is new generation product which can replace Contain heavy metals lead, Choromium traditional anti-rust paint, rust is the use of the results are satisfactory new varieties of paint.Zinc phosphate has great rust resisting performance Zinc phosphate contains no heavy metal, toxicity, pollution or irritation to skin. It has great heat stability, rust-resisting. It is less amount which reduce the cost.
