    Abstract: A method of making magnetizable abrasive particles includes providing a slurry layer disposed on a substrate. The slurry layer has an exposed surface and comprises magnetic particles, a binder precursor, and a liquid vehicle. Abrasive particles are electrostatically contacted with the slurry layer such that they are aligned substantially oriented perpendicular to the surface of the substrate, and are partially embedded within the slurry layer. The liquid vehicle is at least partially removed from the slurry layer and the binder precursor is converted into a binder to provide a magnetizable layer comprising the magnetic particles partially embedded in the binder. The magnetizable abrasive particles ae separated from the releasable substrate. Each magnetizable abrasive particle respectively comprises a portion of the magnetizable layer disposed on a portion of an abrasive particle.

    Abstract: A method of making a mesh abrasive product comprises sequentially: 1) providing a production tool having a mold surface defining a plurality of shaped cavities and filling at least some of the shaped cavities with an abrasive composite precursor slurry, wherein the abrasive composite precursor slurry comprises abrasive particles dispersed within a curable binder precursor; 2) contacting the mold surface with an open mesh backing comprising interwoven threads defining openings, and having first and second opposed major sides; 3) ultrasonically vibrating the abrasive composite precursor slurry; 4) curing the curable binder precursor by exposing it to sufficient actinic electromagnetic radiation to provide isolated shaped abrasive composites contacting and secured to the first major side of the open mesh backing; and 5) separating the mesh abrasive product from the production tool. An open mesh abrasive product preparable by the method is also disclosed.
