Etidronic acid
HEDP is used as a retardant in concrete, scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc. In light woven industry, HEDP is used as detergent for metal and nonmetal.
HEDP (Hydroxyethylidene Diphosphonic Acid) is an odourless organic phosphorus chemical compound. For one thing, it is colourless to yellowish acidic liquid Moreover, HEDP is an organic phosphonic acid corrosion inhibitor. HEDP acid is used in various industrial applications. Such as industrial water treatment corrosion inhibitor and detergents.
HEDP 60, Hydroxyethylidene Diphosphonic Acid 60% - IRO
HEDP 60 Liquid supplied by . It is also called HEDP 60% (Hydroxyethylidene Diphosphonic Acid 60%). Active content is 60%. HEDP 60 is known the superior phosphonic acid chelating agent. Good anti-scaling and hydrolytic stability.
Richard Esser, the manager of the largest wastewater treatment facility in Bonn, explains that the technology in Germany is some of the most advanced in the world.
EP0867410A2 - Cooling water treatment composition
An all-in-one cooling water treatment composition includes a high concentration of peroxide, preferably hydrogen peroxide, in combination with a polyhydric alcohol and a phosphonate to stabilize the peroxide in a concentrated solution. The composition further includes a yellow metal corrosion inhibitor such as aromatic triazole and optionally polymeric dispersants and ferrous metal corrosion

Profile: . offers HEDP acid.Sodium etidronate (HEDP Na) has a good ability to control and complex the metal ions. It can dissolve the oxidized materials. Etidronate sodium has good scale and corrosion inhibition effects even under 250℃.
Phosphonates are highly active specialty chemicals, used as chelants, dispersants and crystal growth inhibitors in a multitude of water related applications. HEDP is a specific type of phosphonate that Solutia markets under the Dequest 2010 brand name for applications such as industrial water & process treatment, detergents and institutional
- What is HEDP NA4?
- HEDP•Na4 is the sodium salt of HEDP, HEDP•Na4 is an good scale inhibitor for calcium carbonate, it can be used in low pressure boiler water system, circulating water system, industrial and municipal cleaning water system and swimming pool.
- Which HEDP tetrasodium is a good scale inhibitor?
- HEDP·Na4 is a good scale inhibitor. This HEDP tetrasodium can be used in low-pressure boilers, circulating, and industrial and municipal cleaning water systems.
- What is HEDP tetrasodium used for?
- HEDP·Na 4 is widely used in circulating cool water systems, medium and low-pressure boilers, and oil field water pipelines as a scale and corrosion inhibitor in fields such as electric power, chemical industry, metallurgy, fertilizer, etc. In the light woven industry, HEDP tetrasodium is used as a detergent for metal and nonmetal.
- 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.
