Hepta sodium salt of Diethylene Triamine Penta (Methylene Phosphonic Acid)

DTPMP•Na7 represents the highest level of chelation technology among these phosphonates, thanks to its seven phosphonic acid groups attached to a diethylene triamine backbone. This structure provides exceptional capacity to sequester metal ions, particularly in alkaline conditions.

This makes DTPMP•Na7 the inhibitor of choice for high-hardness water and systems prone to severe scaling. Its high charge density allows it to efficiently threshold-inhibit the formation of calcium and barium scales. It is especially effective in oilfield applications for controlling barium sulfate scale, providing a robust defense in the most demanding industrial water treatment scenarios.
