  • Patent number: 9308680
    Abstract: A light emitting device that includes a light emitting diode and a multilayer encapsulant is disclosed. The multilayer encapsulant includes a first encapsulant in contact with the light emitting diode and a photopolymerizable composition in contact with the first encapsulant. The first encapsulant may be a silicone gel, silicone gum, silicone fluid, organosiloxane, polysiloxane, polyimide, polyphosphazene, sol-gel composition, or another photopolymerizable composition. The photopolymerizable compositions include a silicon-containing resin and a metal-containing catalyst, the silicon-containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation. Actinic radiation having a wavelength of 700 nm or less can be applied to initiate hydrosilylation within the silicon-containing resins.

  • Patent number: 9187678
    Abstract: Described herein are release layers formed via solventless extrusion. The release layers include a polyolefin and an alkyl dimethicone. The release layers exhibit tailorable release properties from pressure-sensitive adhesives. The release layers are simple to make and require no post-treatment in order to impart the observed release properties. The release layers are adaptable to multilayer extrusion, blown film formation, and cast film formation techniques.
