Detailed Description
Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium
EDTMPS
CAS No. 1429-50-1
Synonym: Dequest 2040
Molecular Formula: C6H12O12N2P4Na8 Molecular weight: 612.13
Structural Formul
Properties:
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.
EDTMPS shows excellent scale inhibition ability under temperature 200. It dissociates 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. It has better antiscale effects to
calcium sulfate and barium sulfate.


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.
Package and Storage:
200L plastic drum, IBC (1000L), customers’ requirement.
Storage for ten months in shady room and dry place.
