PW700 Water-soluble Alloy Anti-rust Pigmen
Property: Solid white powder
Main Components: Modified tripolyphosphate and superfine flake powder
Characteristics: Environmentally friendly, non-toxic, free of heavy metal, and non-combustible. Prepared preparing aqueous pigments are extremely easily dispersible without thickening. Resistance of paint film to salt water ranks first among similar products and it is stable in storage.
Anti-rust Mechanism:
Chemical anti-rust: Modified tripolyphosphate undergoes a complexation reaction with the surface, forming insoluble passive film and inhibiting corrosion to metal base such as steels from the environment.
Physical anti-rust: Superfine flake powder can achieve a physical shielding effect. Main Applications:
It can substitute phosphate anti-rust pigments such as common aqueous zinc phosphate and aqueous aluminum tripolyphosphate and is widely used in steel structure and common industrial parts where aqueous pigments are applied.
