Structural Formula:

Penta Sodium Salt of Amino Trimethylene Phosphonic Acid (ATMP·Na5)


1· Performance and Applications


ATMP·Na5 is the sodium salt solution of ATMP, which can prevent the formation of scaling salts in water, especially calcium carbonate scale.

ATMP·Na5 is used for boiler water treatment, oilfield reinjection water systems, industrial and municipal cleaning water treatment, and metal corrosion inhibition in cooling water treatment.

As a general-purpose low-cost scale inhibitor, ATMP·Na5 has good corrosion inhibition effect and excellent chelating performance.
