摘要： Coated abrasive articles have a composite tie layer. The composite tie layer is preparable by disposing a first polymerizable composition comprising a polyfunctional aziridine on a backing, and disposing a second polymerizable composition comprising at least one acidic free-radically polymerizable monomer and at least one oligomer having at least two pendant free-radically polymerizable groups on the first polymerizable composition, at least partially polymerizing the first and second polymerizable compositions, wherein homopolymerization of the oligomer results in a polymer having a glass transition temperature of less than 50 degrees Celsius.

摘要： 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.
