  • Microwaveable adhesive article and method of use
    Patent number: 5400460
    Abstract: An adhesive article for use in a microwave oven is provided having a hot-melt or heat-curable adhesive substrate, and a susceptor layer of electrically conductive or semi-conductive microwave absorbing material that is disposed on at least a portion of the substrate. The article becomes less absorbent of microwave radiation upon the melting or deformation of the substrate. This article is suitable for adhering one adherend to another by exposing said article containing a hot-melt adhesive substrate to microwave energy.

  • Coated abrasive sheet material with loop material for attachment incorporated therein
    Patent number: 5354591
    Abstract: A sheet of coated abrasive material including a backing having abrasive on one surface and loops projecting from its other surface by which the sheet of coated abrasive material can be held by hooks on the support surface of a pad. The backing comprises a polymeric bonding layer defining its rear surface. The sheet of coated abrasive material comprises a nonwoven sheet of longitudinally oriented fibers having anchor portions bonded in the polymeric bonding layer at spaced bonding locations, and arcuate portions projecting from the rear surface of the backing between the bonding locations to provide the loops.
