50% Amino TrimeXTylene Phosphonic Acid as water treatment agent
Amino TrimeXTylene Phosphonic Acid (ATMP)
CAS No. 6419-19-8 HS：2931000090
Molecular Formula: N(CH2PO3H2)3 Molecular weight: 299.05
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
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.

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 20-60mg/L is preferred.
ATMP liquid: Normally In 250kg net Plastic Drum, IBC drum can also
be used as required ATMP
