  • Patent number: 9117757
    Abstract: Novel compositions and methods of using those compositions to form high refractive index coatings are provided. The compositions comprise a mixture of two silicone polymers, a catalyst, and an inhibitor for the catalyst. The preferred catalyst comprises platinum. Unlike prior art silicone systems, the inventive composition can be provided in a one-part form due to a substantially improved pot life. The compositions can be spin- or spray-applied, followed by baking to crosslink the polymers and form a cured layer. The inventive cured layers have high refractive indices and light transmissions.

  • Patent number: 9018777
    Abstract: An encapsulating composition for a light emitting element, a light emitting diode (LED) and a liquid crystal display device (LCD) are provided. A silicone-cured product included as a main ingredient and a conductivity-providing agent having excellent compatibility and capable of providing superior conductivity can be used to significantly reduce the surface resistivity of the silicone-cured product. Therefore, the encapsulating composition for a light emitting element, the LED and the LCD can be useful in solving the problems regarding attachment of a foreign substance such as dust due to static electricity, and degradation of transparency since the composition has low surface resistivity when used as a semiconductor encapsulation material for an LED, and also in providing a cured product having excellent properties such as light resistance, heat resistance, durability and optical transparency.
