CAS No.: 6419-19-8
ATMP or Aminotris(methylphosphonic acid), 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 ahent in woven and dyeing industries and as metal surface treatment agent.
The solid state of ATMP is crystalline powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts.
