  • Silicone resin composition for optical semiconductors
    Patent number: 9688819
    Abstract: Addition-crosslinkable silicone resin compositions containing a branched organopolysiloxane bearing each of Si—H groups, alkenyl groups, and aryl groups, and also containing blocks of linear organopolysiloxane free of Si—H and alkenyl groups with a chain length of at least three siloxy groups, and further bearing at least one aryl group, serve as excellent potting compositions for electronic devices, particularly LEDs, with high refractive index and optical transmittance, and wide processing latitude.
