HEDP

HEDP
Product Detailed
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 metalssurfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250 Centigrade. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt).
