  • Temporary adhesion of chemically similar substrates
    Patent number: 9034139
    Abstract: A temporary adhesive for reversibly bonding a silicon wafer to a silicon support contains a crosslinkable organopolysiloxanes composition and a fatty acid or salt thereof or fatty acid ester as a release regulator having a density different from the crosslinkable organopolysiloxanes composition of at least 0.1 g/cm3, which upon parting of the wafer from the substrate, the adhesive remains substantially adhered to the substrate.
    Type: Grant
    Filed: July 11, 2012
    Date of Patent: May 19, 2015
    Assignee: Wacker Chemie AG
    Inventors: Andreas Koellnberger, Frank Achenbach
  • SILICONE SOLVENT
    Publication number: 20140336093
    Abstract: Cured or uncured silicones are effectively removed from substrates with minimized substrate corrosion by the use of a silicone dissolver containing a tetralkylammonium fluoride and an inorganic base, dissolved in a solvent.
    Type: Application
