Silica Anti Corrosive Pigment For Industrial Container Anticorrosive Paint
Property:White solid powder
Main Components: Silicon Dioxide
Silica Anti Corrosive Pigment , 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

Rust-proof Mechanism:
Chemical anti-rust: Modified molybdate and phosphate undergo a complexation reaction with painted surface, forming insoluble passive film and inhibiting corrosion to metal base such as steels from the environment.
Main Applications:
Silica Anti Corrosive Pigment helps the formation of passivation layer on the metal surface to be protected. Material for anti-corrosion paint used in container, ship and steel structures.Also for electronic materials.
Suggested dosage:
It is suggested to use between 5%~10%.
