Abstract
The present disclosure describes the use of a polycyclic polysiloxane polymer for light emitting diodes (LEDs). The polymer is characterized by high flame retardancy, high temperature stability, and low moisture and gas permeability. The polymer is useful as a potting compound for encapsulation of phosphors in LED packages, or as a molding resin for producing optical parts for LED light engines, or as a protective coating applied over the light emitting elements.
