[China(Mainland)]
CAS No. 6419-19-8 EINECS No.: 229-146-5
Molecular Formula: N(CH2PO3H2)3 Molecular weight: 299.05
Properties:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale
formation, calcium carbonate in particular, in water system.ATMP has good chemical stability and is
hard to be hydrolyzed in water system. At high concentration, it has good corrosion inhibition.
ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal
power plant and oil refinery plant. ATMP can decrease scale formation and inhibit corrosion of metal
equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as
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. Because of its high purity, it can be used in woven & dyeing industries and
as metal surface treatment agent.

Usage:
ATMP is usually used together with organophosphoric acid, polycarboxylic acid and salt to built all
organic alkaline water treatment agent. ATMP can be used in many different circulating cool water
system. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-60 mg/L is preferred.
