          CAS 1429-50-1 Dequest 2040

          Alias: Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS)

          Molecular formula: C6H12O12N2P4Na8 Relative molecular mass: 612.13

          I. Product Property

          EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under temperature 200. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium sulfate.

          III. Application scope and Usage

          EDTMPS can be used as corrosion inhibitor in circulating cool water system and boiler water. It is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing industry. When used alone, 2~10mg/L is preferred. When built with HPMA by ratio ETDMP:HPMA=1:3, it can be used for low pressure boiler. It can also be built with BTA, PAAS and zinc salt.

          IV. Package and Storage

          It is usually packed in 25kg plastic drum, and can be also determined by users. It can be stored for ten months in shady and dry place under room condition.
