Zinc Phosphate

Chemical name: Zinc phosphate
Molecular formula: Zn3(PO4)2·2H2O
CAS No.: 7779-90-0
Physical Properties: Non-toxic,tasteless, and white powder,indissoluble in water,solyble nitric acid and hydrochloric acid
Application:
Zinc phosphate, as a new generation of antirust pigment, is a new type of nontoxic and harmless white antirust pigment with excellent performance in rust prevention and ideal application effect. It is the best substitute of conventional antirust pigments containing heavy metals such as lead and chrome. it is mainly used in various coating materials for preparation of waterproof,acid-resistant or corrosion preventive coating material such as phenolic paint,epoxy paint,acrylic paint,paste paint and water-soluble resin paint in the field of shipbuilding, automobile,industrial machinery,light metal,household appliances and meteal containers for goods.
Packing and storage: This product is packed with plastic-lined and plastic-coated woven bags or kraft paper sacks,25kg per bag. this product should be kept from breakage,moisture,pollution and contact with acid.
