Applications:
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or Hydroxy Ethylidene Diphosphonic Acid or HEDP is mainly used as a scale and corrosion inhibitor, chelating (sequestrating), deflocculating agent in cooling and boiler water treatment, textile dying detergent etc.

In light woven industry, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP is used together with polycarboxylic acid. It is extensively used in oil well drilling, fracturing or fracking.

Packing & Storage:
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP is generally packed in 250kg plastic drums. It can be packed as per buyers requirement. Store in a cool dry ventilated area, away from incompatible substances. Keep containers tightly closed. Storage for ten months in room shady and dry place.

Properties:
Hydroxy Ethylidene Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP Phosphonate is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals’ surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250℃. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under light and heat. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or Hydroxy Ethylidene Diphosphonic Acid or HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.

The solid state of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP Phosphonate is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.
