HDTMP is a white crystal powder at room temperature, slightly soluble in water (solubility less than 5%). Hexamethylene diamine tetra (methylene phosphonic Acid) is featured by its high inhibition degree and sustaining effect.
HDTMP is a multifunctional antiscalant with excellent effects on CaCO3, CaSO4, BaSO4, and FeO, especially in inhibiting the CaSO4 scale. In addition, it has a good scale inhibition rate and can last for a long effective time.
HDTMP can be used for crush treatment in the oilfield and water treatment in a boiler. However, its chelating ability is comparatively weak. Hexamethylene diamine tetra (methylene phosphonic acid) is suitable for conditions with desirable free metal ions.
