The main composition of dispersant IR-904 is anion polymer. It can be adsorbed on microparticles’ surfaces, resulting in static repulsion, dispersing, and preventing sedimentation and coarse turn-back. In addition, IR-904 is little foaming, innocuous, non-corrosiveness, and non-hazardous.

IR-904 is used as a chelant in papermaking coating, building coating, concrete retarder, water reducer, woven, and dyeing. Its performance can reach that of SN-5040. Adding IR-904 to the slurry during the grinding process of bolus alba, lime carbonate, pottery clay, titanium pigment, french chalk, barium sulfate, coal-water slurry, etc., the viscosity can be largely reduced, and the dispersed slurry is stable.
