SD-904 aqueous dispersant
Alias: Viscosity Reduer, Water Reducer, Grind Aider

The main composition of dispersant SD-904 is anion polymer. It can adsorb on surface of microparticles resulting in static repulsion, resulting in disperse and preventing sedimentation and coarse turn-back. SD-904 is little foaming, innocuous, non-corrosiveness and non-hazardous.
SD-904 is used as chelant in papermaking coating, building coating, concrete retarder, water reducer, woven and dyeing. Its performance can reach to that of SN-5040. Adding SD-904 to slurry during 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.
