ATMP LA

Good, general purpose, cost-effective scale inhibitor, Good corrosion inhibition with zinc and phosphates. Good chelant.

Chemical name:Amino Tri(Methylene Phosphonic Acid)

 

Abbreviation: ATMP LA

Molecular Formula: C3H12NO9P3

Molecular Weight: 299

 

CAS Number: 6419-19-8

 

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

ATMP 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 agent in woven and dyeing industries and as metal surface treatment agent.Recommended Uses: ATMP is usually used together with organophosphoric acid, polycarboxylic acid and salt to built all organic alkaline water treatment agent. ATMP can be used in many different circulating cool water system. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-60mg/L is preferred.
