Patent number: 5922784Abstract: A coated abrasive article comprises a backing, a first binder (i.e., a make coat) on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, a polyfunctional acrylate component, and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The invention also relates to a method of producing such coated abrasive articles and a surface-treated porous cloth material.Type: GrantFiled: September 2, 1998Date of Patent: July 13, 1999Assignee: Minnesota Mining and Manufacturing CompanyInventors: Robert J. DeVoe, Gregg D. Dahlke, Kimberly K. Harmon, Craig A. Masmar

Patent number: 5690705Abstract: Precisely shaped composites and methods for making these composites are disclosed. The method of this invention comprises the steps of:(a) providing a production tool having a plurality of cavities;(b) providing a dispensing means capable of introducing a binder precursor comprising a thermosetting resin into the cavities;(c) providing a means, within a curing zone, for at least partially curing the binder precursor;(d) introducing the binder precursor into at least a portion of at least two of the cavities;(e) continuously moving the production tool through the curing zone to at least partially cure the binder precursor to provide a solidified, handleable binder;(f) removing the binder from said at least one cavity; and(g) converting the binder into precisely shaped composites.Steps (f) and (g) can be conducted simultaneously. The composites are bonded to a backing to form a coated abrasive article.Type: GrantFiled: June 24, 1996Date of Patent: November 25, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Gary L. Holmes, Scott R. Culler, David H. Hardy, William A. Hendrickson, Thomas P. Klun, Kimberly K. Harmon, Robert V. Heiti, Kathryn M. Spurgeon, Charles J. Studiner, III
