Silicone resin composition and its use, a silicone resin, a silicone resin-containing structure, and the optical semiconductor element encapsulation material

摘要

PPROBLEM TO BE SOLVED: To provide a silicone resin composition which can maintain transparency and is excellent in sulfur resistance, a method for using the same, a silicone resin, a silicone resin-containing structure, and an optical semiconductor device sealed body. PSOLUTION: The silicone resin composition includes a component (A): a polysiloxane having at least two alkenyl groups each combined with a silicon atom, a component (B): a polysiloxane crosslinking agent having at least two hydrogen groups each combined with a silicon atom, a component (C): a hydrosilylation reaction catalyst, and a component (D): a zinc compound. The component (D) is contained in an amount of 0.1-5 pts.mass based on 100 pts.mass of the sum of the component (A) and the component (B). PCOPYRIGHT: (C)2011,JPO&INPIT
