Applications

ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. in water system ,it can prevent scale formation, particularly for calcium carbonate. in water, ATMP has good chemical stability and is hard to be hydrolyzed. At high concentration, it has good corrosion inhibition.

ATMP can be used in thermal power plant, recirculated cooling water of oil refinery, and recycle waterflood system of oilfield.. 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, easily soluble in water, easy moisture absorption,

particularly suitable for using in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing industries and as metal surface treatment agent.
