Properties:
Amino Trimethylene Phosphonic Acid has excellent chelation, low threshold inhibition, and
lattice distortion ability. It can prevent scale formation, calcium carbonate,
in particular, in the water system. ATMP has good chemical stability and is
hard to be hydrolyzed in a water system. At high concentrations, it has good
corrosion inhibition.
Amino Trimethylene Phosphonic Acid is used in industrial circulating cool water system
and oilfield water pipeline in thermal power plant and oil refinery plant
fields. Amino Trimethylene Phosphonic Acid can decrease scale formation and inhibit the 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 ATMP is crystal powder, soluble in
water, easily deliquescence, suitable for usage in winter, and freezing
districts. Its high purity can be used in woven & dyeing industries and as
a metal surface treatment agent.

Usage:
Amino Trimethylene Phosphonic Acid is usually used together with organophosphorus acid,
polycarboxylic acid, and salt to build all organic alkaline water treatment
agents. ATMP can be used in many different circulating cool water system. A
dosage of 1-20mg/L is recommended. As a corrosion inhibitor, the dosage of
20-60mg/L is preferred.
