Document Type and Number:
WIPO Patent Application WO/2017/217510
Kind Code:
A1
Abstract:
The present invention is an addition reaction type polyorganosiloxane composition which can be cured rapidly at room temperature. A cured product of the composition exhibits high elongation, excellent stress relaxation properties and good reliability under conditions of high temperature and high humidity and exhibits excellent reliability in cold/heat cycling. The composition contains: (A1) a straight chain polysiloxane containing alkenyl groups at both terminals; (B1) a straight chain polysiloxane containing SiH groups at both terminals; (B2) a crosslinkable polyorganohydrogensiloxane; one or more types selected from the group consisting of (A2) a straight chain polysiloxane containing an alkenyl group at one terminal and (B3) a straight chain polysiloxane containing a SiH group at one terminal; and (C) a platinum-based catalyst. The content of component A2 is 0-60 parts by weight relative to a total of 100 parts by weight of components A1 and A2, and the value of (HB1+HB2+HB3) / (ViA1+ViA2) (in the formula, ViA1, ViA2, HB1, HB2 and HB3 are as disclosed in the description) is 0.6-2.2.
