EDTMPS is used in circulating cool water system and boiler water as corrosion inhibitor. EDTMPS is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing industry. When EDTMPS is used alone, 2~10mg/L dosage is preferred. EDTMPS can also be used in combination with BTA, PAAS and zinc salt.
