ABSTRACT:
A binder precursor dispersion suitable for use in producing abrasive articles, the dispersion consisting essentially of a polymerizable resin, filler particles, and modifying particles, wherein the modifying particles are present in an amount sufficient to reduce the viscosity of the same binder precursor dispersion; a method of making a coated abrasive comprising the steps of (a) coating a backing material with a slurry, the slurry consisting essentially of a polymerizable resin, abrasive particles, and modifying particles, wherein said modifying particles are present in an amount sufficient to reduce the viscosity of the same slurry; (b) subjecting the coated backing of step (a) to conditions sufficient to cure the polymerizable resin; and a method of reducing a sedimentation rate of mineral particles by adding the modifying particles.
