Abstract
A composition includes: (I) an alkenyl functional, phenyl-containing polyorganosiloxane, an Si—H functional phenyl-containing polyorganosiloxane, or a combination thereof; (II) a hydrogendiorganosiloxy terminated oligodiphenylsiloxane having specific molecular weight, an alkenyl-functional, diorganosiloxy-terminated oligodiphenylsiloxane having specific molecular weight, or a combination thereof; and (III) a hydrosilylation catalyst. A light emitting device is made by applying the composition onto a light source followed by curing. The composition provides a cured material with mechanical properties suited for use as an encapsulant for a light emitting device.
