Amino trimethylene phosphonic acid (ATMP) has excellent chelation, low threshold inhibition, and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in a water system. Amino trimethylene phosphonic acid has good chemical stability and it is hard to be hydrolyzed in a water system. At high concentrations, it has good corrosion inhibition.
ATMP is used in the industrial circulating cool water system of thermal power plant and oil refinery plant. Amino trimethylene phosphonic acid can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as a chelating agent in woven and dyeing industries and as a metal surface treatment agent.
The solid-state of amino trimethylene phosphonic acid is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing industries and as a metal surface treatment agent.

ATMP is usually used together with organophosphoric acid, polycarboxylic acid, and salt to built all organic alkaline water treatment agents. ATMP can be used in many different circulating cool water systems. A dosage of 1-20mg/l is recommended. As a corrosion inhibitor, the dosage of 20-60mg/l is preferred.
