HPAA 2-Hydroxyphosphonocarboxylic Acid
HPAA (2-Hydroxyphosphonocarboxylic Acid) enhances zinc solubility and exhibits excellent corrosion inhibition properties, outperforming HEDP and EDTMP. It is primarily used as a corrosion and scale inhibitor in open recirculating cooling water systems, and also serves as an effective scale dispersant.
Product Performance
(1) Good chemical stability, resistant to hydrolysis, and not easily degraded by acids or alkalis
(2) HPAA demonstrates excellent synergistic effects and compatibility with organic phosphonates, copolymers, zinc salts, etc., with particularly enhanced performance when combined with zinc salts
(3) Suitable for water with pH ranging from 7.0 to 9.5, ideal for use as a corrosion inhibitor in low-alkalinity, low-hardness corrosive water conditions in southern regions
(4) HPAA exhibits good thermal stability, with low decomposition rates even at high temperatures up to 200°C
(5) Safe and reliable to use, non-toxic and pollution-free
