product description

Product Description of Zinc phosphate CAS#7779-90-0

Zinc Phosphate is a high-purity industrial chemical with a minimum purity of 99%. It is a white, odorless crystalline powder featuring superior thermal and chemical stability. It has a melting point of around 900 °C and decomposes when heated to boiling. At 20 °C, its vapor pressure is negligible, with a relative density of 3.99. Zinc Phosphate is practically insoluble in water and ethanol, but freely soluble in inorganic acids and ammonia solutions. It remains stable under normal storage and handling conditions, and should be kept away from strong acids and alkalis for chemical compatibility.


Product Application of Zinc phosphate CAS#7779-90-0

Zinc Phosphate is widely adopted as a key anticorrosion pigment in protective coating systems, frequently compounded with barium metaborate and strontium chromate. It is commonly formulated into thin wash primers and corrosion-inhibiting primers. In such systems, phosphate or chromate pigments are dispersed in synthetic polymer binders like vinyl chloride copolymers, delivering reliable surface protection and long-lasting corrosion resistance.
