ATMP

Amino Trimethylene Phosphonic Acid
(ATMP, ZF112)

[CAS No.] 6419-19-8 Dequest: 2000

Molecular Formula: N(CH2PO3H2)3 Molecular weight: 299.05

Structural Formula:



Properties:

This product has better antiscale performance than that of polyphosphate through its excellent chelating ability, low threshold inhibition and lattice distortion process. It can prevent scale formation in water system. ATMP has good stability and is hard to be hydrolyzed in water system. At high concentration, it has good corrosion inhibition.

This product is widely used in industrial circulating cool water system and oilfiled water pipeline, it can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in weave and dyeing industries and as metal surface treatment agent.
