HPAA48%AS No:23783-26-8)

Product Description

Specifications 2-Hydroxyphosphonocarboxylic Acid

CAS: 23783-26-8 very strong corrosion inhibition

5~8 times better than HEDP and EDTMP

HPAA shows good chemical stability, but easy to hydrolysis. Its acid-base can not easily be destroyed. Therefore, it performs of safe, reliable and non-toxic pollution in application. HPAA can improve zinc salt solubility. It shows a very strong corrosion inhibition, 5~8 times better than HEDP and EDTMP. HPAA can be used together with other organic corrosion and scale inhibitors to perform a better corrosion and scale inhibition as an all-organic Water Treatment formula. Specification:
