Abstract
Sluuries and binder precursor dispersions suitable for use in producing abrasive articles are presented. Slurries comprise a polymerizable resin which is preferably addition polymerizable, abrasive particles, and modifying particles, wherein the modifying particles are present in an amount sufficient to reduce the viscosity of the slurry. Abrasive articles incorporating cured versions of the slurries and dispersions are presented, as well as methods of making the articles and of reducing sedimentation rate of mineral particles (abrasive or filler).
Claims8
A coated abrasive of the type having a flexible backing having an abrasive coating thereon, wherein the abrasive coating is derived from a slurry which consists essentially of from about 20 to about 95 dry weight percent polymerizable resin, from about 30 to about 70 dry weight percent abrasive particles, and from about 0.01 to about 30 dry weight percent modifying silica particles by, based on dry weight of said slurry.
