Product Description

Product Introduction
2-Hydroxyphosphonocarboxylic Acid (HPAA) is a new type of organic phosphine scale and corrosion inhibitor. Besides good scale inhibition performance, it also has good corrosion inhibition performance. In addition, it is particularly effective for stabilizing zinc salt corrosion inhibitors, and is often used in conjunction with sulfonate copolymers (AA/AMPS) and zinc salts. Another advantage is its low phosphorus content, which is in line with the current trend of low phosphorus. At present, it is mainly used in compound formulations of scale and corrosion inhibitors that require high corrosion inhibition performance.
