Potassium Salt of Amino Trimethylene Phosphonic Acid (ATMP Kx)


The equivalent of ™ Dequest 2004A is the partial potassium salt of amino trimethylene phosphonic acid. ATMP Kx has a better dissolution ability than that of sodium salt. ATMP Kx can inhibit scale formation, calcium carbonate in particular, in the water system. ATMP Kx can be used in the oilfield refill water system.
