ATMP or aminotris(methylenephosphonic acid) is a phosphonic acid. It has chelating properties.
Properties
ATMP 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 systems. ATMP is the phosphonate analog of nitrilotriacetic acid.
Applications
- Detergents and cleaning agents
- Water treatment
- Scaling inhibition
- Chelationru:Кислота нитрилотриметилфосфоновая
