Structural Formula

Properties

HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better.
