2-Hydroxy Phosphonoacetic Acid (HPAA) 50% Water Treatment For Corrosion Inhibitor

2-Hydroxy Phosphonoacetic Acid HPAA (CAS 23783-26-8) is chemically stable,hard to be hydrolyzed,hard to be destroyed by acid or 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 and EDTMP.When built with low molecular polymers,its corrosion inhibition effect is even better.
