<p>A multi-component room-temperature-curable silicone elastomer composition comprises (A) a diorganopolysiloxane including (A-1) a diorganopolysiloxane capped at both molecular terminals with alkoxysilyl groups or hydroxysilyl groups and (A-2) a diorganopolysiloxane capped at only one molecular terminal by an alkoxysilyl group or a hydroxysilyl group and at the other molecular terminal with an alkyl group or an alkenyl group, having a viscosity at 25° C. of 20 to 1,000,000 mPa·s. The composition further comprises (B) a silicon-bonded aryl group-containing alkoxysilane, (C) an organic compound having at least two alkoxysilyl groups in one molecule (and being free of siloxane bonds), and (D) a curing catalyst. Components (A), (B), (C), and (D) are not contained simultaneously in the composition. The composition generally shows sufficient usable life at low temperatures, curing properties with low dependence on temperature and excellent curability at low temperatures, and excellent adhesion.</p> |
