HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. HEDP can dissolve the oxidized materials on these metals’ surfaces. Phosphonate HEDP shows excellent scale and corrosion inhibition effects under temperature 250?.HEDP has good chemical stability under high pH value, hard to be hydrolyzed.
