Victoria: victoria at thwater dot net

CAS No. 6419-19-8
Molecular Formula: N(CH2PO3H2)3 Molecular weight: 299.05

Properties of ATMP:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. ATMP 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, ATMP 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, ATMP can be used in woven & dyeing industries and as metal surface treatment agent.
