Product Description


Low Heavy Metal Zinc Phosphating Chemicals 7779-90-0 Zinc Phosphate Primer


water based coating paint pigmt zinc phosphate coating rust Zinc Phosphate

Low-heavy-metal Zinc phosphate ( 7779-90-0 ) zinc phosphate primer

Low-heavy-metal Superfine Zinc Phosphate 7779-90-0


As a white coloring pigment, it is flexible to match any top coat through color mixing as required, which can simplify the preparation process of painting and coating significantly.
With low heavy metal, good thermal stability and excellent rust prevention, zinc phosphate is nontoxic, environment-friendly, not irritative to skin and cost-effective due to little required in coating materials

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.Zinc Phosphate renders coating materials excellent rust-preventing performance and good resistance to water




•Zinc Phosphate is used in corrosion resisting primers and undercoats.It is widely used in various coating materials for preparation of waterproof, acid-resistant or corrosion preventive coating materials such as phenolic paint, epoxy paint, acrylic paint, paste paint.


Zinc Phosphate is used in manufacturing of Zinc Rich Paint Formulations.


Zinc Phosphate is used manufacturing of Fertilizers.


•Zinc Phosphate is used for water-soluble resin paint in the fields of shipbuilding, automobile, industrial machinery, light metal, household appliances and metal containers for foods.
