High Performance Aluminum Tripolyphosphate Cost Competitive
Aluminum tripolyphosphate SH-A208
1. It is zinc-free white anti-rust pigment with low heavy metal
contents, and it is in line with EU environmental protection
2. 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
3. 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.
