1-Hydroxy Ethylidene-1, 1-Diphosphonic Acid (HEDP) 60%

Amino trimethylene phosphonic acid (ATMP) is a synthetic phosphonic acid compound used primarily as a scale and corrosion inhibitor in water treatment applications. It features a trimethylene backbone and amino groups, enhancing its chelating properties. ATMP is effective in preventing mineral deposits in industrial systems, making it valuable in sectors like oil, gas, and cooling water management. Its stability and low toxicity further contribute to its widespread use.
