ATMP-AminoTrimethylene Phosphonic Acid
CAS No.: 6419-19-8
Alias: Aminotrimethylene phosphonic acid
Molecular formula: N(CH2PO3H2)3
Property
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.
