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.
