Properties:
1.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.
2.It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance,have excellent scale inhibition ability under temperature 200°C
3.EDTMPS shows better antiscale effects to calcium sulfate and barium sulfate.

Application field:
1.EDTMPS can be used as corrosion inhibitor in circulating cool water system and boiler water.
2.It is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing industry.

Usage:
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.
