Title:
RESIN COMPOSITION FOR ELECTRICAL/ELECTRONIC COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2016/163333
Kind Code:
A1
Abstract:
The present invention relates to a resin composition for electrical/electronic components, which contains (A) a polyorganosiloxane that has a viscosity of 20-3,000 cP at 23°C and contains a mercaptoalkyl group bonded to a silicon atom, (B) a polyorganosiloxane that contains an aliphatic unsaturated group and is composed of (B1) a linear polyorganosiloxane represented by formula (I), and optionally (B2) a branched polyorganosiloxane which is composed of an SiO4/2 unit, an R'3SiO1/2 unit and an R'2SiO2/2 unit, and optionally an R'SiO3/2 unit, and wherein at least three R' moieties are aliphatic unsaturated groups in each molecule, (C) a photoreaction initiator, (D) a silica that has a chemically treated surface, a BET specific surface area of 50-250 m2/g and a pH of 5.0-9.0, and (E) a polyoxyalkylene glycol, in which the alkylene unit is a linear or branched alkylene group having 2-4 carbon atoms, and/or a derivative of the polyoxyalkylene glycol. In this connection, the ratio of the number of mercaptoalkyl groups in the component (A) to the total number of aliphatic unsaturated groups in the component (B) is 0.45-2.00; the content of the component (D) is 0.5-26 parts by mass relative to 100 parts by mass of the component (B); the content of the component (E) is 0.001-1.0% by mass relative to the total mass of the components (A)-(E); and the viscosity of the resin composition at 23°C is 500-100,000 cP.
