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

Patent number: 4773920Abstract: Coated abrasive comprising a backing and abrasive grain adhered to said backing by means of a binder. The binder is prepared from a composition that is curable by free-radical polymerization. The composition contains abrasive grain suspended therein at the time the composition is coated onto the backing. The abrasive exhibits high endurance for extended periods of use. The coated abrasive is prepared by a method comprising the steps of:(a) providing a coatable composition comprising a binder curable by free-radical polymerization, said composition having lapping size abrasive grains suspended therein,(b) coating said composition on a backing, and(c) curing said composition by means of free-radical polymerization.Type: GrantFiled: March 18, 1987Date of Patent: September 27, 1988Assignee: Minnesota Mining and Manufacturing CompanyInventors: Jonathan N.
