Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS)

EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor.
2. Performance Index:
Ingredient: Maleic Anhydride-Acrylic acid copolymer
Appearance: brown yellow transparent liquid
Solid content (%):

48.0
Free ion monomer (count as maleic acid)%

9.0
Density (20 °C) g/cm3:

1.18
PH value (1% aqueous solution): 2.0 ~ 3.0

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 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 In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
