Structural Formula:
Product performance:
EDTMPS is a nitrogenous organic polyphosphonic acid, belongs to 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 eight 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.
Specification:

Range of application:
It can be used as scale and corrosion inhibitor in circulating cooling water systems and boiler water、chelating agent in non-cyanide electroplating、chelating agent in textile dyeing industry and peroxide’s stabilizer.
Usage:
When add EDTMPS into circular cooling water independent, the dosage is 2-10mg/L. After mixing together with HPMA, can be used as water treatment in lower pressure boiler. EDTMPS can also be mixed together with BTA、PAAS、Zinc salt and so on.
Package and Storage:
Normally In 30kg or 250kg net Plastic Drum, IBC drum can also be used as required.
Storage for ten month in room shady and dry place.
