    摘要: A structured abrasive article includes a backing having a structured abrasive layer disposed on and secured thereto. The structured abrasive layer includes shaped abrasive composites that comprise abrasive particles and nonionic polyether surfactant dispersed in a crosslinked polymeric binder. The abrasive particles have a mean particle size of less than 10 micrometers. The nonionic polyether surfactant is not covalently bound to the crosslinked polymeric binder and is present in an amount of from 2.5 to 3.2 percent by weight based on a total weight of the shaped abrasive composites. The structured abrasive articles are useful for abrading a workpiece.

    摘要: A method for making an abrasive article having at least two abrasive coatings having different abrasive natures. The abrasive natures can differ, for example, by abrasive particle size, abrasive particle type, abrasive particle shape, filler, surfactant, or coupling agent. In another embodiment, the abrasive article can be a structured abrasive article comprising abrasive composites. In another aspect of the invention, the article can have a coating having a single abrasive nature, where the composites comprising the coating are free of abrasive particles.

    摘要: 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).
