Cas No. :1429-50-1
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 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. 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? 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 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. Safety Protection: EDTMPS is for weak alkali when using should be avoid contact with eye and skin, once contacted, flush with water.
