Properties
Amino trimethylene phosphonic acid has excellent chelation. Its threshold inhibition is low, and chemical stability is high. ATMP is an excellent antiscalant and chelating agent to most metal ions like Ca, Ba, Mg, Fe, and Pb, especially Calcium Carbonate (CaCO3). It is difficult to hydrolyze in the water system and can distort the lattice. In a higher concentrated system, ATMP is also a good corrosion inhibitor.
ATMP acid is used in industrial circulating cool water systems of thermal power plants and oil refinery plants. ATMP can decrease scale formation and inhibit the corrosion of metal equipment and pipeline. In addition, ATMP acid can be used as a chelating agent in woven and dyeing industries and as a metal surface treatment agent.
Usually, it is compounded with organophosphorus acid/salt and polycarboxylic acid/salt. Amino trimethylene phosphonic acid, solid as crystal powder, can also be supplied for cold areas, particularly in water. It is easy to dissolve. ATMP is suitable for usage in winter and freezing districts. Because of its high purity, ATMP can be used in woven & dyeing industries and as a metal surface treatment agent.
