CURED SILICONE WITH HIGH LIGHT TRANSMITTANCE, CURABLE SILICONE FOR PREPARING SAME, DEVICES AND METHODS

摘要

A non-resinous curable polyorganosiloxane composition consisting essentially of non-resinous ingredients that comprise non-resinous ingredients (A), (B), (C), and (D): (A) a first polyorganosiloxane polymer containing vinyl groups only on terminal ends of the first polyorganosiloxane polymer, only on pendant positions of the first polyorganosiloxane polymer, or on terminal ends and pendant thereon (i.e., some on terminal ends and others pendant thereon); (B) a multivinyl-functional silicon monomer for forming cluster crosslinks; (C) a SiH functional crosslinker; and (D) a curing reaction catalyst. A cured polyorganosiloxane, free-standing light guide, composite light guide, optoelectronic devices, and luminaires prepared therefrom. A method of transmitting light.
