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


IR-241 is a copolymer of carboxylic group, hydroxylic group, and a sulfonic acid group. Acrylic acid/acrylate/phosphonic acid/sulfosalt copolymer has good scale inhibition performance to calcium phosphate and calcium carbonate.

Acrylic acid/acrylate/phosphonic acid/sulfosalt copolymer has good synergic effects with other agents. IR-241 is used as a scale inhibitor and dispersant in circulating cool water system and built with an organophosphate.
