Patent number: 6848986Abstract: The present invention is directed to a method of making a three-dimensional fixed abrasive article, and a three dimensional fixed abrasive made thereby. The method comprises providing an abrasive composition comprising a plurality of abrasive particles and a binder precursor. The binder precursor comprises a polymerizable material consisting essentially of an ethylenically unsaturated material having one or more terminal functional groups of the same type of reactive functionality, a photoinitiator, and a thermal initiator. The abrasive composition is then applied onto a backing. The method then comprises at least partially curing the binder precursor by activating the photoinitiator, and further curing the binder precursor by activating the thermal initiator to provide a three-dimensional fixed abrasive.Type: GrantFiled: April 30, 2003Date of Patent: February 1, 2005Assignee: 3M Innovative Properties CompanyInventors: Philip E. Kendall, Soon C. Park, Wesley J. Bruxvoort, Scott R. Culler, Jerry W. Williams
