Abstract
An abrasive composite is presented having a controller rate of erosion, the composite comprising abrasive particles dispersed in the binder, wherein the binder comprises an addition polymerized resin having clay particles dispersed therein. The abrasive composite may be adhered to various substrates, including paper, cloth, polymeric films, and nonwovens. The clay particles allow the binder, and thus the composite, to controllably erode upon abrasion of a workpiece, thus exposing fresh abrasive particles to the workpiece. Coatable compositions comprising clay particles dispersed in a binder precursor composition, and optionally containing abrasive particles, are also described, as well as methods of making and using the composites and articles.
