HMDTMPA.Kx CAS 38820-59-6(K.x-6)
As a premier global chemical supplier, Sinochem delivers premium industrial-grade HMDTMPA.Kx (also known as Hexamethylenediamine Tetra(Methylene Phosphonic Acid) Hexapotassium Salt). Engineered specifically for harsh and highly demanding industrial water environments, HMDTMPA.Kx stands out as an exceptional, highly efficient scale inhibitor and chelating agent. It exhibits an outstanding aqueous dissolution profile and is specifically optimized to operate in water systems characterized by high pH values, extreme alkalinity, and elevated thermal conditions.
Unlike standard phosphonates that suffer from reduced efficiency or precipitation under severe alkaline stresses, our HMDTMPA.Kx maintains long-term molecular stability. It provides critical threshold inhibition against stubborn mineral deposits, ensuring the structural integrity and operational efficiency of high-pressure boilers, reverse osmosis (RO) membranes, and industrial heat exchangers.
- Targeted Calcium Sulfate Mitigation: Demonstrates an extraordinary scale inhibition efficiency against calcium sulfate (CaSO4), preventing crystal nucleation even in hyper-saline water matrices.
- Extreme Alkaline Tolerance: Remains completely functional and chemically stable across high-pH regimens where conventional organic phosphonic acids fail or lose chelating power.
- Outstanding Dissolution Profile: Dissolves rapidly and thoroughly in water across all temperature ranges, eliminating the risk of compound-induced equipment clogging or line blockages.

Hexamethylenediamine Tetra(Methylene Phosphonic Acid) Potassium Salt Applications
- Industrial Circulating Cooling Water & High-Pressure Boilers: HMDTMPA.Kx is widely utilized as a core antiscalant component in industrial circulating cooling water systems. It is particularly irreplaceable in high-pressure boiler water systems operating under severe alkaline stresses. By binding with scale-forming cations, it significantly extends equipment lifespans and reduces unscheduled descaling shutdowns.
- Reverse Osmosis (RO) Membrane Antiscalant: In desalination plants and advanced industrial wastewater reclamation facilities, HMDTMPA.Kx serves as a high-performance reverse osmosis membrane antiscalant. It prevents severe membrane fouling caused by calcium sulfate and calcium carbonate deposits, ensuring consistent permeate water quality and lowering membrane backwash frequencies.
- Heavy-Duty Industrial Detergents & Chelating Agents: Thanks to its excellent alkaline stability and threshold effect, HMDTMPA.Kx functions as a premium builder and corrosion inhibitor in industrial detergents, bottle-washing formulations, and metal surface cleaning agents. It effectively sequesters metal ions, preventing redeposition on treated surfaces.
- Harsh Oilfield Water Reinjection Systems: In oilfield water treatment, particularly during secondary oil recovery involving deep well water reinjection, HMDTMPA.Kx acts as a powerful downhole scale inhibitor. It cleanly mitigates complex mineral scaling within high-salinity formation water, preventing subterranean pipe constrictions.
Q1: Why is HMDTMPA.Kx preferred over standard phosphonates like ATMP or HEDP for calcium sulfate scale?
A: Standard phosphonates like ATMP or HEDP suffer from a dramatic decrease in scale inhibition efficiency when exposed to high-pH and high-calcium environments. HMDTMPA.Kx possesses a unique hexamethylenediamine core that provides superior structural flexibility, allowing it to maintain high threshold inhibition specifically against calcium sulfate (CaSO4) under harsh alkaline conditions.
Q2: What is the significance of supplying HMDTMPA as a hexapotassium salt solution?
A: Neutralizing HMDTMPA into its hexapotassium salt form drastically enhances its water solubility and prevents the active acid from precipitating out of the solution in low temperatures. This delivery format ensures ease of dosing, immediate dissolution in automated chemical injection systems, and excellent compatibility with neutral-to-alkaline water formulations.
Q3: Can HMDTMPA.Kx be formulated alongside other water treatment polymers?
A: Yes. HMDTMPA.Kx exhibits excellent synergistic compatibility with other water treatment chemicals, including polyacrylic acid (PAA), polymaleic acid (HPMA), and zinc salts, allowing formulators to build multi-action, high-efficiency corrosion and scale inhibition packages.
