Products Description of Amino Tris(Methylene Phosphonic Acid) CAS#6419-19-8

Amino Tris(Methylene Phosphonic Acid) (ATMP) is an organic phosphonic acid compound widely used as an antiscalant and functional chemical additive. Its solution can be effectively removed from membrane concentrates through iron-coated waste filtration sand.

ATMP also serves as a cement retarder and is applied in construction-related processes to help regulate cement setting behavior. In addition, it can react with aluminum surfaces to form a protective coating, which effectively inhibits the reaction between evaporated aluminum thin films on glass or silicon substrates and deionized water.

Amino Trimethylene Phosphonic Acid CAS#6419-19-8

Product Application of Amino Tris(Methylene Phosphonic Acid) CAS#6419-19-8

Amino Tris(Methylene Phosphonic Acid) (ATMP) is widely used in water treatment systems, including cooling water systems in power plants, refineries, petrochemical facilities, and fertilizer plants, as well as oilfield injection water systems. It is especially suitable for high-hardness, high-calcium, low-concentration multiple-cycle systems and oil pipeline applications with high salinity and poor water quality conditions.

By effectively inhibiting corrosion and scale formation, ATMP helps reduce the risk of damage to metal equipment and pipelines, improving operational stability and service life.

In the textile printing and dyeing industry, ATMP is used as a metal ion chelating agent and a metal surface treatment agent, providing reliable performance in industrial processing applications.
