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.

Packing & Storage:

Hydroxy Ethylidene 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.
