Zinc phosphate application:
Environmentally friendly anti-corrosion and rust-preventing pigments: These are currently the most important high-efficiency, non-toxic anti-rust pigments in industry. They are used as a base material for alkyd resins, phenolic resins, epoxy resins, and other coatings, and are widely used in anti-corrosion primers, epoxy paints, and water-based anti-corrosion coatings for automobiles, ships, bridges, and industrial machinery.
Metal surface phosphating treatment: Used as a core component of phosphating solutions before coating steel surfaces, significantly enhancing the adhesion and corrosion resistance of the upper coating film.
Dental cementitious materials: Pharmaceutical-grade zinc phosphate is commonly used in dental clinics as a dental cement, lining material, or filling material.
Catalysts and production aids: Used as a solid catalyst in certain chemical synthesis processes; it can also be used as a synergistic additive for flame retardants.
Zinc phosphate Packaging and Shipping
25kg/bag or customized according to customer needs.
Zinc phosphate Storage
Store in a cool, dry, and well-ventilated warehouse. It is chemically inert under standard parameters; keep packages sealed to protect against humidity and bag rupture.
