HexaMethyleneDiamineTetra (MethylenePhosphonic Acid), HDTMP

Properties:

HDTMP is a white crystal powder at room temperature, slightly soluble in water (solubility less than 5%). HexaMethyleneDiamineTetra (methylene phosphonic Acid) is featured by its high inhibition degree and sustaining the effect.

HDTMP is a multifunctional antiscalant with excellent effect on CaCO3, CaSO4, BaSO4, and FeO. Especially in inhibiting CaSO4 scale. It has a high scale inhibition rate and can last for a long effective time.

HDTMP can be used for crush treatment in the oilfield and for water treatment in a boiler. However, its chelating ability is comparatively weak. HexaMethyleneDiamineTetra (methylene phosphonic acid) is particularly suitable for the conditions with desirable free metal ions.
