Curable silicone composition, encapsulant and optical semiconductor device |
| abstract |
[Problem to be Solved] It is desired to provide a curable silicone composition which exhibits excellent thixotropy and has reduced dimensional change and shrinkage factor upon curing. [Means for Solving the Problem] The problem is solved by a curable silicone composition comprising: (A) an alkenyl group-containing organopolysiloxane having at least two alkenyl groups per molecule; (B) an organohydrogenpolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; (C) an epoxy group-containing resinous organopolysiloxane represented by the average unit formula (I): (R 1 3 SiO 1/2 ) f (R 2 2 SiO 2/2 ) g (R 1 SiO 3/2 ) h (SiO 4/2 ) i (XO 1,2 ) j {in the formula ( I) R 1 are in each case independently halogen-substituted or unsubstituted monovalent hydrocarbon groups, with at least two R 1 being alkenyl groups; R 2 are in each case independently halogen-substituted or unsubstituted monovalent hydrocarbon groups or epoxy group-containing organic groups, at least one R 2 being an epoxy group-containing organic group; X is a hydrogen atom or an alkyl group; 0 ≤ f <1;0<g<1; 0 ≤ h <0.9; 0 ≤ i <0.5; and 0<j<0.5; f + g + h + i + j = 1.0; h + i >0; and j/(f + g + h + i + j) >0.05}; and (D) a curing catalyst. |
