Synomyms:
Phosphonic acid, (nitrilotris(methylene))tris-;

ATMP is an organophosphonic acid water treatment agent, chelating and sequestering agent.

It has good chelating, inhibition effects. It can prevent scale-forming salts in water, especially calcium carbonate scale. ATMP is stable in water, has good corrosion inhibition when compounded with zinc and phosphate water treatment chemicals.

We provide ATMP sodium salts, ATMP-Na too.
