  • Curable organopolysiloxane composition, encapsulant and semiconductor device
    Patent number: 11028266
    Abstract: A curable organopolysiloxane composition, a Light Emitting Diode (LED) encapsulant and a semiconductor device, employ a curable organopolysiloxane composition containing a branched organopolysiloxane bearing alkenyl groups and aryl groups, a linear organopolysiloxnae bearing terminal Si—H functionality, and a low molecular weight component having at least one alkenyl group. As an encapsulant, the composition displays improved stability.
    Type: Grant
    Filed: August 12, 2016
    Date of Patent: June 8, 2021
    Assignee: WACKER CHEMIE AG
    Inventors: Hyun-Kwan Yang, Young-Hyuk Joo, Young-Jin Kim, Arvid Kuhn
  • Siloxane resin compositions
    Patent number: 10696846
    Abstract: Unique compositions containing organopolysiloxanes having both silicon-bonded hydrogen and aliphatically unsaturated groups exhibit robust processing characteristics and provide coatings or encapsulations of high transparency which can withstand numerous temperature cycles without failure.
    Type: Grant
    Filed: December 7, 2016
    Date of Patent: June 30, 2020
