Abstract
An adhesive or encapsulant composition, having a siloxane polymer having a molecular weight of from 300 to 150,000 g/mol and having a viscosity of from 1000 to 100,000 mPa-sec at 5 rpm viscometer and at 25° C., and a curing agent that aids in curing the siloxane polymer upon the application of ultraviolet light. The composition is transmissive to visible light with an optical transmissivity of 95% or more in the visible spectrum at a thickness of 1 mm or less, and wherein the siloxane polymer is a material formed without hydrosilylation and has less than 5 mol % of Si—OH groups compared to all groups bound to Si therein, and substantially no Si—H bonds.
