Amino Tri (Methylene Phosphonic Acid)
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.
