2-Hydroxy Phosphonoacetic Acid (HPAA) CAS: 23783-26-8
PUBLISH:admin READ:1517

Molecular Formula: C2H5O6P

CAS Number: 23783-26-8

Application Notes:

HPAA 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 EDTMPA.Na . When built with low molecular polymers, its corrosion inhibition 5 effect is even better.

Recommended Uses:

It is mainly used as cathode corrosion inhibitor in oilfield refill water system, in fields such as steel & iron, petrochemical, power plant and medical industries. When built with zinc salt, the effect is even better.


Package and Storage:

Normally in 200L HDPE drum or 1000L IBC. 

Storage for ten months in room shady and dry place.

Safety Protection:

Acidity, avoid contact with eye and skin, once contacted, flush with water.
