Property and Uses
HPAA has good chemical stability, is not easily hydrolyzed, is not easily destroyed by acids or alkalis, is safe and reliable to use, non-toxic and pollution-free, can improve zinc solubility, and has good corrosion inhibition, with corrosion resistance higher than HEDP and EDTMP
This product is mainly used as a cathodic corrosion inhibitor for metals, widely applied in the steel, petrochemical, electric power, and pharmaceutical industries for corrosion inhibition and scale inhibition in circulating cooling water systems, suitable for low-hardness, corrosion-prone water in southern China
