Product Description

ATMP(liquid and solid), HEDP(liquid and solid), EDTMPS, EDTMPA(high purity), DTPMPA, PBTCA, PAPE, HPAA, HMDTMPA, PAPEMP, BHMTPMPA *-Hydroxyphosphonocarboxylic Acid (HPAA) CAS No *********8 Molecular Formula: C2H5O6P Molecular weight: **6 Properties: *-Hydroxyphosphonocarboxylic Acid (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 **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 % *7.***0.0 Phosphorous acid(as PO**-)% 4.0 max Density (*0℃)g/cm3 1.*0 min pH(1% solution) 1.**3.0 Usage: *-Hydroxyphosphonocarboxylic Acid (HPAA) is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better. Package and Storage: Normally In **0kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.
