Abstract
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.
