Industrial Paint Coil Coating Application Silica Anti Corrosive Pigment Compare to SNCZ XCA02
Characteristics:
1. It is zinc-free white anti-rust pigment with low heavy metal contents, and it is in line with EU environmental protection standards.
2. It is stable in acid resins, and it is special suitable for application systems that sensitive to zinc ions.
Scope of application: It is suitable for most solvent systems, aqueous alkyds systems and aqueous acrylic systems.
3. The main antirust components are polyphosphate ions and phosphate ions dissociated from aluminum tripolyphosphate, and they can form passivation film of iron polyphosphate and iron phosphate in the anode area, so it has dual anti-corrosion function for a long term.
Recommended dosage:
5 % - 8 % for solvent systems and 5 % - 10 % for aqueous systems.
