1. A curable silicone composition comprising a reaction product of a reaction of:
(I) a clustered functional polyorganosiloxane having at least one radical curable group selected from an acrylate group and a methacrylate group that comprises a reaction product of a reaction of:
a) a polyorganosiloxane having an average, per molecule, of at least 2 aliphatically unsaturated organic groups,b) a first polyorganohydrogensiloxane having an average, per molecule, of 4 to 15 silicon atoms and at least 4 silicon bonded hydrogen atoms per aliphatically unsaturated organic group in component a),c) a first reactive species having, per molecule at least one aliphatically unsaturated organic group and one or more curable groups selected from acrylate groups and methacrylate groups,in the presence of d) a first hydrosilylation catalyst and e) a first isomer reducing agent, wherein the first isomer reducing agent e) comprises a carboxylic silyl ester or 2,6-Di-tert-butyl-4-(dimethylaminomethyl)phenol; (II) a silicone reactive diluent comprising a reaction product of a reaction of:
a) a second polyorganohydrogensiloxane having an average of 10 to 200 silicon atoms per molecule, andb) a second reactive species having, per molecule, at least 1 aliphatically unsaturated organic group and 1 or more curable groups,in the presence of c) a second isomer reducing agent and d) a second hydrosilylation catalyst; and (III) a radical initiator. |
