<p>Bonded abrasive articles and methods of making and using same are presented, the bonded abrasive articles comprising abrasive particles dispersed throughout and adhered within an elastomeric polyurethane binder, at least a portion of the abrasive particles adhered to the polyurethane binder by a silane coupling agent. The silane coupling agent is preferably coated onto the abrasive particles before they are mixed with the uncured polyurethane resin. The articles of the invention exhibit excellent smear- and wear-resistance and provide improved abrasion efficiency.</p> |
