IR-613 Acrylic Acid/Acrylate/Sulfosalt Terpolymer


Acrylic acid/acrylate/sulfosalt terpolymer is a scale inhibitor and dispersant containing sulfosate and polyelectrolyte. This terpolymer has strong acid, weak acid, and non-ion groups. Acrylic acid/acrylate/sulfosalt terpolymer (IR-613) suits high temperatures, high pH, hardness, and alkaline conditions.

IR-613 has good scale inhibition for ferric oxide, calcium phosphate, zinc phosphate, and calcium carbonate. In addition, it has a good synergic effect with polyphosphate, zinc salt, and other agents.

Acrylic acid/acrylate/sulfosalt terpolymer can be used as a scale inhibitor and dispersant in the industrial circulating water system, oilfield refill water system, and boiler water.
