Patent number: 6753359Abstract: The present invention involves the use of powder coating methods to form coated abrasives. In one embodiment, the powder is in the form of a multiplicity of binder precursor particles comprising a radiation curable component. In other embodiments, the powder comprises at least one metal salt of a fatty acid and optionally an organic component that may be a thermoplastic macromolecule, a radiation curable component, and/or a thermally curable macromolecule. In either embodiment, the powder exists as a solid under the desired dry coating conditions, but is easily melted at relatively low temperatures and then solidified also at reasonably low processing temperatures. The principles of the present invention can be applied to form make coats, size coats, and/or supersize coats, as desired.Type: GrantFiled: December 20, 2001Date of Patent: June 22, 2004Assignee: 3M Innovative Properties CompanyInventors: Ernest L. Thurber, Eric G. Larson, Gregg D. Dahlke, Robert J. DeVoe, Alan R. Kirk, Mark R. Meierotto, Roy Stubbs

Patent number: 6277160Abstract: A method for making an abrasive article having at least two abrasive coatings having different abrasive natures. The abrasive natures can differ, for example, by abrasive particle size, abrasive particle type, abrasive particle shape, filler, surfactant, or coupling agent. In another embodiment, the abrasive article can be a structured abrasive article comprising abrasive composites. In another aspect of the invention, the article can have a coating having a single abrasive nature, where the composites comprising the coating are free of abrasive particles.Type: GrantFiled: May 5, 2000Date of Patent: August 21, 2001Assignee: 3M Innovative Properties CompanyInventors: Roy Stubbs, Scott R. Culler, Mara E. Liepa, Donna W. Bange, John D. Haas
