  • What is HEDP phosphonic acid?
  • HEDP (Hydroxyethylidene Diphosphonic Acid) 60% is a widely used organic phosphonic acid compound in water treatment applications. It is a highly effective scale and corrosion inhibitor known for its excellent chelating properties.
  • What is HEDP 1 hydroxy ethylidene 1 diphosphonic acid (HEDP)?
  • Home » Corrosion Inhibitors & Scale Inhibitor » HEDP/1-Hydroxy Ethylidene-1,1-Diphosphonic Acid Hydroxyethylidene Diphosphonic Acid (HEDP) is a highly efficient water treatment agent widely used as a scale and corrosion inhibitor. Packing: Liquid: 250kg/ drum, 1.25mt/IBC, or as customers’ requirement. Solid: 25kg/bag, customers’ requirement.
  • Why is HEDP used in copper ECMP process?
  • HEDP can maintain a stable pH environment and easily generates complexes with metal ions to suppress corrosion, even at 250 °C. Furthermore, HEDP forms coordination compounds with other water treatment agents, so it is widely used in the copper ECMP process.
  • How HEDP is used in non cyanide electroplating?
  • In non-cyanide electroplating, HEDP is used as a chelating agent. The dosage of 1-10mg/l is preferred as a scale inhibitor, 10-50mg/l as a corrosion inhibitor, and 1000-2000mg/l as a detergent. Usually, HEDP is used together with polycarboxylic acid. HEDP liquid: 200L plastic drum, IBC (1000L), customers’ requirement.
