  • Coated abrasive article containing an electrically conductive backing
    Patent number: 5560753
    Abstract: A coated abrasive article having a backing comprising a sufficient amount of an electrically conductive material therein to reduce the buildup of static electricity during the use of the article. In another aspect, a method of making the same is taught.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: October 1, 1996
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Herbert W. Schnabel, Scott J. Buchanan, Richard G. McAllister
  • Coated abrasive having an overcoating of an epoxy resin coatable from water
    Patent number: 5556437
    Abstract: A coated abrasive product having a coating comprising a composition formed from an epoxy resin that is capable of being coated from water, a curing agent, and a grinding aid dispersed in the epoxy resin. It is preferred that the coat containing the epoxy resin and the grinding aid be the outermost coat of the coated abrasive product, e.g. the size coat or supersize coat, in order to position the grinding aid in direct contact with the workpiece being abraded.
    Type: Grant
    Filed: August 16, 1995
    Date of Patent: September 17, 1996
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Chong S. Lee, Scott J. Buchanan
  • Coated abrasive having an overcoating of an epoxy resin coatable from water
    Patent number: 5549719
    Abstract: A coated abrasive article having a coating comprising a composition formed from an epoxy resin that is capable of being coated from water, a curing agent, and optionally a grinding aid dispersed in the epoxy resin. It is preferred that the coat containing the epoxy resin and the grinding aid be the outermost coat of the coated abrasive article, e.g. the size coat or supersize coat, in order to position the grinding aid in direct contact with the workpiece being abraded.

  • Method of making a coated abrasive article containing a conductive backing
    Patent number: 5328716
    Abstract: A method of making a coated abrasive article having an electrically conductive backing is taught, wherein electrically conductive material is incorporated into a coated abrasive backing. The coated abrasive article made by this method has a reduced tendency to accumulate static electric charge in the abrasive article during abrading of a workpiece.

    Inventor: Scott J. Buchanan
  • Abrasive article having vanadium oxide incorporated therein
    Patent number: 5203884
    Abstract: An abrasive article (i.e., a coated abrasive article or a three-dimensional, low density abrasive article) having a sufficient amount of vanadium oxide incorporated therein to provide having a reduced tendency to buildup static electricity during the abrading of a workpiece. Preferably, the abrasive article further comprises a compatible binder (preferably, a sulfonated polymer) to aid in securing the vanadium oxide to the abrasive article. In another aspect, a method of making the same is taught.
    Type: Grant
