DTPMP
The CUBLEN D series (DTPMP) represents the most versatile phosphonic acid in the CUBLEN product range and impresses with its outstanding price–performance ratio. DTPMP is an excellent inhibitor for mineral deposits (for example CaCO3, BaSO4, SrSO4) and a powerful complexing agent. Selected DTPMP products are certified according to the North American standard NSF/ANSI 60 for use in the production of drinking water.
