PRODUCT OVERVIEW

Product Description

Water Treatment Agent ATMP-Na5 40% is a clear to light-yellow liquid based on the pentasodium salt of aminotrimethylene phosphonic acid. ATMP-Na5 is used in industrial water-treatment systems where scale control, corrosion inhibition, and metal-ion chelation are required. It is particularly associated with controlling calcium carbonate scale and can be applied in circulating cooling-water systems and related industrial water-treatment formulations. Its commercial quality is evaluated through ATMP active content, ATMP-Na5 active content, total phosphoric acid, chloride content, pH, iron content, and density.
