HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safe in use, non-toxic and pollution-free. HPAA can improve zinc solubility. Its corrosion inhibition efficiency is 5-8 times higher than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better.
