Purposes: anti-rust coatings prepared by the sub-calcium phosphate is non-toxic, strong adhesion, good flexibility, strong hiding power, salt water, etc., anti-rust properties and the traditional anti-rust coating of red lead is better than zinc chrome yellow, zinc phosphate, phosphoric acid, aluminum and other anti-corrosion coatings. In addition, sub-calcium phosphate can be used as a polymerization catalyst and fertilizer. Used as food additives and animal nutrition agent, used in the manufacture of pharmaceuticals, can be as anti-oxidants, and analytical reagents.
Packing: net weight 25kg, lined with PE bag, coat plastic woven bags. Product sealed and stored in a dry place, dark place.
