aqueous dispersant(th-904) alias: viscosity reduer, water reducer, grind aider properties: the main composition of dispersant th-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. aqueous dispersant(th-904) is little foaming, innocuous, non-corrosiveness and non-hazardous. aqueous dispersant(th-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 th-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. specification: items index appearance colorless to light yellow viscous liquid solid content % 40.0 min ph value (2% water solution) 8.0~11.0 density (20℃)g/cm3 1.20 min viscosity(25℃)mpa.s 200—600 usage: the dosage of 0.2-2% is preferred (solid/solid), the optimal dosage should be determined by experiment. package and storage: normally in 250kg net plastic drum, ibc drum can also be used as required. storage for ten months in room shady and dry place.
