ATMP 95% CAS 6419-19-8 Amino Trimethylene Phosphonic Acid Water Treatment Agent



ATMP 95%, also known as Amino Trimethylene Phosphonic Acid, is an organic phosphonic acid widely used as a water treatment scale and corrosion inhibitor. It has the chemical formula N(CH₂PO₃H₂)₃, CAS No. 6419-19-8, and a molecular weight of 299.05.


Sinobio ATMP 95% is supplied as a white crystalline powder with an assay of at least 95%. It is readily soluble in water and has strong chelating properties due to its three phosphonic acid groups. ATMP can interact with metal ions such as calcium, magnesium and iron, helping control inorganic scale formation and metal corrosion in water treatment systems.


ATMP provides effective scale inhibition and dispersion, particularly for calcium carbonate scale. It is suitable for applications where stable water treatment performance is required, including industrial circulating cooling water, boiler water treatment, oilfield reinjection water, reverse osmosis systems and heat-exchange systems.


In addition to water treatment, ATMP can be used as a metal-ion chelating agent in textile printing and dyeing, metal surface treatment, electroplating pretreatment and selected refinery processes.


Sinobio supplies ATMP 95% for industrial applications with standard 25 kg bag packaging. Samples, bulk orders and customized requirements can be discussed according to customer specifications.



ATMP Application


1. Circulating Cooling Water

ATMP can be used in industrial circulating cooling water systems to help control scale and corrosion in equipment and heat-exchange systems.


2. Boiler Water Treatment

It helps reduce scale formation in boiler systems and supports heat-transfer efficiency.


3. Oilfield Reinjection Water

ATMP can be used in oilfield reinjection water treatment to control problematic metal ions and scale formation.


4. Reverse Osmosis Systems

ATMP can be used to help control membrane surface scaling in selected RO water-treatment systems.


5. Textile Printing & Dyeing

As a metal-ion chelating agent, ATMP can help reduce unwanted interactions between metal ions and dyes.


6. Metal Surface Treatment

It can be used in metal cleaning, electroplating pretreatment and related surface-treatment processes.
