| titleOfInvention | Curable white silicone formulation, a reflective material for optical semiconductor module, and optical semiconductor device |
| abstract | [Objective] To provide a white curable silicone composition that provides excellent elongation characteristics while providing sufficiently great hardness, which as a result can provide a cured product having excellent toughness. n [Solving Means] The abovementioned objective can be achieved by a white curable silicone composition comprising: (A) alkenyl group-containing resinous organopolysiloxane which is represented by an average composition formula: (R 1 3 SiO 1/2 ) a (R 1 2 SiO 2/2 ) b (R 1 SiO 3/2 ) c (SiO 4/2 ) d (X O 1/2 ) e , where, in the formula, R 1 are each independently a monovalent hydrocarbon group, while at least two R 1 are alkenyl groups, X is a hydrogen atom or an alkyl group, 0 ≦ a≦ 0.7, 0 ≦ b ≦ 0.2, 0 ≦ c ≦ 0.3, 0 ≦ d ≦ 0.8 , and 0 ≦ e ≦ 0.2, a + b + c + d = 1.0, and c + d > 0 are satisfied; (B) linear alkenyl group-containing organopolysiloxane which is represented by R 2 R 3 2 SiO(R 3 2 SiO) n SiOR 2 R 3 2 , where, in the formula, R 2 is an alkenyl group, R 3 are each independently a monovalent hydrocarbon group other than an alkenyl group, and n is an integer of 50 or greater; (C) organohydrogenpolysiloxane having at least two hydrogen atom-bonded silicon atoms in one molecule; (D) a catalyst for curing reaction; and (E) a white pigment, wherein the component (A) is included in an amount of 20 mass% or more based on the total mass of the organopolysiloxane components, and the alkenyl group content in the components (A) to (C) is 1.7 mass% or less. |
