IR-2100 Carboxylate-sulfonate Copolymer Dispersant


IR-2100 carboxylate-sulfonate copolymer dispersant is a good anti-scaling efficiency against calcium carbonate, sulfate, and oxalate. In addition, IR-2100 has exceptional stability in the presence of hypochlorite and very strong dispersant activity.

IR-2100 carboxylate-sulfonate copolymer is good thermal stability, contains no phosphorus – meets discharge after legislation requirements. (similar to ACUMER 2100)

IR-2100 is a copolymer that functions as a scale inhibitor and dispersant by combining strong acid (sulfonate) and weak acid (carboxylate), providing optimal anti-scale/dispersant efficiency. IR-2100 carboxylate-sulfonate copolymer can be mainly used in industrial water treatment and pulp& water processes.

Packing and storage:

Usually, IR-2100 can be packed in a 250kg net plastic drum. The IBC drum can also be used as required.

200L plastic drum 1000L IBC

Storage for ten months in a room shady and dry place.
