HL-106 2-hydroxyphosphonylacetic acid HPAA
Product performance:
HPAA is an organic dirt-resistant corrosion withlow phosphorus content. HPAA molecules also contain radonic acid groups,carboxylic acids, and hydroxyl groups. They have excellent stains of corrosion,and they are particularly prominent in soft water and high -hardness water.HPAA has the characteristics of low phosphorus, good thermal stability, lowtoxicity, etc., and has good phase solubility and synergies with some commonlyused water quality stabilizers, and has a better complexity effect with zincsalt.

Product Usage:
HPAA is mainly used as a metal cathode corrosionagent, which is widely used in the circulating cooling water system in thesteel, petrochemicals, power, pharmaceutical and other industries. Essence
HPAA can be reproduced into a dirt -resistantcorrosion agent with common organic pheasant, polymer and other monomers, whichis better with the use of corrosion performance with zinc salt.
Packing and Storage:
The net weight 25ibc or 250ibc plastic barrel isstored in a cool and dry place for two years of storage.
Safety Protection:
This product is an acidic liquid, which has acertain corrosion and irritation for the skin and eyes. When operating theoperation, the operator should wear protective gloves, masks and eye masks toprevent inhaling droplets and avoid direct contact with the skin. Once splashedon the body, it splashes on the body. ,Rinse a lot of water immediately, andshould be sent to the hospital for treatment immediately in the case ofcritical emergencies.
