2-hydroxy Phosphonoacetic Acid (Hpaa)

We are engaged in manufacturing, exporting and supplying excellent quality 2-Hydroxy Phosphonoacetic Acid (HPAA) to our valuable clients.
CAS No. 23783-26-8
Other Names: 2-Hydroxyphosphonocarboxylic Acid;Hydroxyphosphono-acetic acid; 2-HYDROXY PHOSPHONOACETIC ACID; HPA;
Molecular Formula: C2H5O6P
Molecular Weight: 156.00
Properties:
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.

Usage:
HPAA is mainly used as cathode corrosion inhibitor in circulating cool water systems in fields such as steel & iron, petrochemcal, power plant and medical industries, suitable for low hardness and easily corrosive water quality. When built with zinc salt, the effect is even better.
Safety:
Acidity. Avoid contact with eye and skin. In case of contact, flush with water immediately.
