Title:
ORGANOPOLYSILOXANE COMPOSITION
Document Type and Number:
Japanese Patent JPH0762244
Kind Code:
A
Abstract:

PURPOSE: To obtain an organopolysiloxane composition useful as a potting material for electronic parts, etc., providing a soft uncured mixture having excellent workability and curing properties and high mechanical strength after curing, comprising a specific compound as part of a base polymer and a given amount of a compound as a curing agent.

CONSTITUTION: This composition comprises (A) a straight-chain polyorganosiloxane containing alkenyl groups at both ends, (B) a branched polyorganopolysiloxane of formula I [R1 is (substituted) monofunctional hydrocarbon not containing aliphatic unsaturated bond; R2 is alkenyl; (a) is 0-3 and (b) is 0-2; when the whole Si-containing units p+q+r=1, (p), (q) and (r) are 0.1≤(p)≤0.5, 0≤(q)≤0.5, 0.3≤(r)≤0.8] containing 0.1-10mmol R2 based on 1g of the component B in which at least two R2s exist in the molecule, (C) a polyorganohydrogensiloxane containing a unit of formula II [R3 is (substituted) monofunctional hydrocarbon; (c) is 0-02; (d) is 1 or 2; c+d is 1-3] and two or more hydrogen atoms bonded to Si and (D) a catalyst.
