hedp What are the product features

HEDP is an organophosphonate corrosion inhibitor. HEDP shows multifunctional properties that includes scale inhibition and corrosion inhibition. HEDP is noted for excellent CaCO3 inhibitor and water hardness stabilizer. HEDP is very good complexing agent for metal ions like Fe, Cu, and Zn.

HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. When built together with other water treatment chemicals, HEDP shows good synergistic effects. HEDP shows excellent stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. HEDP shows excellent scale and corrosion inhibition effects under temperature 250℃. HEDP acid/alkali and chlorine oxidation tolerance are better than that of other organophosphonate (salts).

HEDP can dissolve the oxidized materials on these metals' surfaces.

HEDP solid form is a white crystalline powder with a melting point of 198-200°C, suitable for usage in winter and freezing districts. Highly soluble in water, acids, alkalis, methanol and ethanol. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.
