Product Description

Product Description

Name: HEDP
CAS: 2809-21-4
Chemical formula:C2h8o7p2
Appearance: Colorless transparent liquid

Etidronic acid (HEDP) is a new type of chloride free electroplating complexing agent, which is used as the main agent to stabilize the water quality in the circulating cooling water system and plays a role of corrosion and scale inhibition.
This product is one of the organic polyphosphonic acid free water tablets, and there are also other varieties of this type of product produced domestically, such as amino trimethylene phosphonic acid (ATMP): [CH2PO (OH) 2] 3N, and  (EDTMP), etc. Organic polyphosphonic acid is a type of water treatment agent developed in the late 1960s and confirmed around the 1970s. The emergence of this type of treatment agent has taken a significant step forward in water slicing technology. Compared with organic polyphosphates, organic polyphosphonate free acids have the characteristics of chemical stability, difficult hydrolysis, high temperature resistance, small dosage, and scale moderation. It is a type of cathodic corrosion inhibitor and a type of non chemical equivalent scale inhibitor; When used in combination with other water treatment agents, it exhibits ideal synergistic effects. It has excellent chelating properties for many metal ions such as calcium, magnesium, copper, zinc, etc., and even has good deactivation effects on inorganic salts of these metals such as CaSO4, CaCO3, MgSiO3, etc. Therefore, it is widely used in water treatment technology.
