HPAA

2-Hydroxyphosphonocarboxylic Acid (HPAA)
CAS No 23783-26-8
Molecular Formula: C2H5O6P Molecular weight: 156

Properties:
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 EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better.
Specification:
items index
Appearance Dark umber transparent viscous liquid
Solid content % 47.0-50.0
Phosphorous acid（as PO33-）% 4.0max
Density （20℃）g/cm3 1.30min
