Hexamethylenediamine Tetramethylene Phosphonic Acid (HMTPMP)
HMTPMP is a high-performance organophosphonate scale and corrosion inhibitor used in cooling water and oilfield systems. Its hexamethylene backbone provides superior tolerance to calcium hardness and excellent threshold inhibition against sulfate and carbonate scales. It also offers moderate iron and manganese chelation to prevent deposition.
