Amino Trimethylene Phosphonic Acid (ATMP)

Properties
ATMP has good chelation, low limit inhibition, and lattice distortion effects. It can prevent the formation of scale salts in water, especially the formation of calcium carbonate scale. ATMP has stable chemical properties in water and is not easily hydrolyzed. When the concentration is high in water, it has a good corrosion inhibition effect.
ATMP is used for circulating cooling water in thermal power plants, refineries, and oilfield reinjection water systems. It can reduce corrosion and scaling of metal equipment or pipelines. ATMP is used as a metal ion chelating agent in industries such as textile printing and dyeing, and can also be used as a metal surface treatment agent.
ATMP solid is white granular, easily soluble in water, hygroscopic, easy to transport and use, especially suitable for cold winter areas.
