SILOXANE COMPOSITIONS SUITABLE FOR FORMING ENCAPSULANTS

摘要

A composition of the present invention includes an organopolysiloxane component (A) comprising at least one of a disiloxane, a trisiloxane, and a tetrasiloxane, and has at least one of an alkyl group and an aryl group and has an average of at least two alkenyl groups per molecule. Component (A) has a number average molecular weight less than or equal to 1500 (g/mole). The composition further includes an organohydrogensiloxane component (B) having at least one of an alkyl group and an aryl group and having an average of at least two silicon-bonded hydrogen atoms per molecule. Component (B) has a number average molecular weight less than or equal to 1500 (g/mole). The composition yet further includes a catalytic amount of a hydrosilylation catalyst component (C). A product of the present invention is the reaction product of the composition, which may be used to make a light emitting diode.
