Detailed Description:
Cas No. :1429-50-1
1, 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 is miscible
with water, innocuous and none
pollution to environment, has
good chemical stability and
temperature 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.
2, Specification:
conform to HG/T 3538-2003

3、Application range&using method
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:
Normally EDTMPS packed with 25kg
net Plastic Drum, or packed as
customer’s required. Storage for
ten months in room shady and dry
place.
