Product Description

Phosphate Anti-rust Pigment-Zinc Phosphate solubility in nitric acid and hydrochloric acid

 

Natural forms of zinc phosphate include minerals hopeite and parahopeite, Zn3(PO4)2•4H2O. A somewhat similar mineral is natural hydrous zinc phosphate called tarbuttite, Zn2(PO4)(OH). Both are known from oxidation zones of Zn ore beds and were formed through oxidation of sphalerite by the presence of phosphate-rich solutions. The anhydrous form has not yet been found naturally

 

 

Preservative Zinc phosphate

Zinc Phosphate has the advantage of non toxic nature over other Corrosion Resistant Pigments much as Zinc Chromate, Zinc Tetroxy Chromate and Barium Chromate.

 

EXCELLENT INTER-COAT ADHESION

 

The use of Zinc Phosphate in Primers promotes excellent inter-coat adhesion, particularly under conditions of high humidity.
