ATMP details
ATMP
Amino Trimethylene Phosphonic Acid
Brief introduction
Chemical formula: N(CH2PO3H2)3
Molecular weight: 299.05
CAS: 6419-19-8
EINECS: 2931900090
Use
It can be used as retarder for CSA cement
ATMP has good chelation, low limit inhibition and lattice distortion effects. It can prevent the formation of scale from scale-forming salts in water, especially the formation of calcium carbonate scale. ATMP has stable chemical properties in water and is not easily hydrolyzed. When the concentration in the water is high, it has a good corrosion inhibition effect.
