high Performance Silica Dioxide Replacement Compound Anti-rust Pigments For Coil Coatings
Property:
White solid powder
Main Components:
Modified Silicon Dioxide.
Main Features:
Environmentally friendly, non-toxic, free of heavy metal, extremely easily dispersible, and non-combustible. Resistance to salt water and spray salt of prepared paint film ranks first among similar products.
Main Applications:
The product is widely used. Its performance surpasses traditional anti-rust pigments such as zinc molybdate, aluminum tripolyphosphate, zinc phosphate and calcium hydrophosphate, and is widely applied in such fields as rolled steels, mechanical and electrical products, steel structure, ships and oil pipelines.
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.
Usage:
Dispersed and directly blend with base, auxiliary materials, additives and solvents.
Suggested dosage:
It is suggested to use between 5%~10%.
