Abstract
Endless coated abrasive articles having a splice. In general, the coated abrasive articles comprise a backing having abrasive grains bonded thereto by one or more layers of binder. This invention also provides a method of making the splice by using radiation curable adhesives, e.g., acrylated urethanes, and radiation energy to cure the adhesives. The radiation curable splice adhesive essentially solvent-free. Consequently, the time required for the solvent to flash off is eliminated and solvent removal is no longer an environmental concern. By utilizing a source of radiation energy, the splice adhesive can be solidified in less than one minute. Because the splice adhesive is fully solidified, coated abrasive belts can be packaged immediately after the splice is formed.
