  • Encapsulation resins
    Patent number: 7943719
    Abstract: Curable polyorganosiloxanes are provided that cure in the absence of a hydrosilylation catalyst. The cured polyorganosiloxanes have increased stability and can be used as encapsulation resin is at a temperature far lower than 300° C., have excellent light transmission properties (colorless transparency. in a wavelength region of from ultraviolet light to visible light, light resistance, heat resistance, resistance to moist heat and UV resistance, and do not generate cracks and peeling even in use over a long period of time.
    Type: Grant
    Filed: February 28, 2008
    Date of Patent: May 17, 2011
    Assignees: The Regents of the University of California;, Mitsubishi Chemical Company
    Inventors: Craig J. Hawker, Rosette G. Guino, Keiichi Seki, Kenichi Takizawa, Yutaka Moti
  • Method of producing encapsulation resins
    Patent number: 7732553
    Abstract: A process is provided for producing curable polyorganosiloxanes where noble metal oxides are used as hydrosilylation catalysts. The noble metals can be used in solid granular form or as part of a fixed bed, and do not form part of the final curable composition or cured product. The cured polyorganosiloxanes have increased stability and can be used as encapsulation resins at a temperature far lower than 300° C., have excellent light transmission properties (colorless transparency) in a wavelength region of from ultraviolet light to visible light, light resistance, heat resistance, resistance to moist heat and UV resistance, and do not generate cracks and peeling even in use over a long period of time.
