IR-241 Acrylic Acid/Acrylate/Phosphonic Acid/Sulfosalt Tetra-copolymer


IR-241 is a copolymer of the carboxylic group, hydroxylic group, and sulfonic acid group. Therefore, it has good scale inhibition performance to calcium phosphate and calcium carbonate.

IR-241 has good synergic effects with other agents. IR-241 is used as a scale inhibitor and dispersant in circulating cool water systems and is built with organophosphates.
