ABSTRACT:
This invention provides an abrasive article comprising abrasive agglomerate particles and a bond system. The abrasive agglomerate particles comprise a plurality of abrasive grains bonded together by means of a first binder. The abrasive agglomerate particles can be bonded to a backing by means of a first bond system. The first bond system comprises a second binder and a plurality of hard, inorganic particulates dispersed therein. A second bond system may be applied over the abrasive agglomerate particles. The second bond system comprises a third binder and a plurality of hard inorganic particulates dispersed therein. The bond systems of the invention are generally made by combining at least a curable binder precursor with hard, inorganic particulates. The invention also provides methods of making and using the above abrasive articles.
