High Performance Silicon Dioxide Use Anti-corrosive Pigments For High-end Industrial Paint
Property: White solid powder
Main Components: Modified Silicon Dioxide
Main Features:
Environmentally friendly, non-toxic, free of heavy metal, non-combustible, extremely easily dispersible in medium and high-grade aqueous pigments, and no thickening. The prepared aqueous paint film is resistance to salt water and ranks first among similar products and it is very stable in storage.
Rust-proof Mechanism:
Chemical anti-rust: Modified phosphate zinc molybdate and organic nitrogen-modified zinc salt which has a sustained release effect undergo a complexation reaction with the substrate surface, forming insoluble passive film and inhibiting corrosion to metal base like steels from the environment.
Main Applications:
It is mainly used in preparation of aqueous pigments. Its performance surpasses that of traditional aqueous anti-rust pigment, such as modified zinc tripolyphosphate, aqueous phosphate zinc, zinc chrome, and strontium yellow. It is widely used in corrosion protection of automobile parts and engineering vehicles and steel structure which have high requirements for environmental protection.
Usage: Add the product after emulsion systems are beaten, and grind the product after other systems areadded.
Suggested dosage:
It is suggested to use between 5%~10%.
