PURPOSE:The titled composition, obtained by adding a specific monohydric alcohol to a polydiorganosiloxane, capable of exhibiting improved rubber elasticity and remarkably improved adhesive property on curing, and suitable for a sealing material capable of exhibiting the characteristics thereof without shrinking even in curing at a high temperature. CONSTITUTION:An adhesive polyorganosiloxane composition obtained by incorporating (A) 100pts.wt. polydiorganosiloxane having terminal groups blocked with silanol groups and a viscosity of 100-200,000cSt, at 25 deg.C with (B) 0.1- 30pts.wt. organosilicon compound, containing aminoxy groups, and having average more than two organoaminoxy groups in the molecule, (C) 5-300pts.wt. inorganic filler and (D) 0.01-10pts.wt. unsaturated monohydric alcohol, expressed by the formula ROH (R is a primary or secondary hydrocarbon selected from alkenyl), and having a vapor pressure >=0.1mm.Hg, preferably 0.5-30mm.Hg, at 20 deg.C. |
