    摘要: A coated abrasive article comprises a backing, a first binder on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable preferably, melt-processable resin containing an epoxy resin, an ethylene-vinyl acetate copolymer, and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The above binder precursors of the invention are preferably free of homopolymers and copolymers of olefinic monomers. In another aspect, the invention also describes an energy curable first binder precursor containing an epoxy resin, an ethylene-vinyl acetate copolymer, 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 backing material.

    摘要: An article adapted for sealing a discontinuity in a surface. The article includes a melt-flowable composition that flows and seals the discontinuity when the article is heated to a sufficient temperature and a polymeric cap controlling the melt-flow behavior of the melt-flowable composition to substantially confine the melt-flowable composition to the area underneath the cap, when the article is heated to a temperature sufficient to cause the melt-flowable composition to flow, and then cooled.

    摘要: A magnetic recording disk that includes an annular recording medium disk bonded to a hub with a pressure sensitive adhesive. The pressure sensitive adhesive bonds the disk to a flange portion of the hub. The present invention also includes a method of bonding an annular recording medium disk to a hub, comprising the steps of: providing a crosslinkable hot-melt adhesive containing a fluorescent dye; applying a quantity of the crosslinkable adhesive to the hub at a specified application temperature; and using a light detector to measure the amount of adhesive on the hub.
