<p><P>PROBLEM TO BE SOLVED: To provide a room temperature-curable polyorganosiloxane composition which has satisfactory surface curing property, and is excellent in adhesiveness, particularly, in adhesion durability at high temperature and high humidity. <P>SOLUTION: The composition contains: 100 pts.wt. of (A) a polyorganosiloxane mixture composed of (A1) a polyorganosiloxane blocked with trialkoxysilyl groups at both terminals and (A2) a polyorganosiloxane blocked with dialkoxysilyl groups at both terminals, the ratio of the number of bifunctional silyl groups at terminals in the component (A2) to the total number of functional silyl groups at terminals in the component (A) being 40-80 mol%; 1-50 pts.wt. of (B) diorganopolysiloxane; 1-300 pts.wt. of (C) an inorganic filler; 0.5-15 pts.wt. of (D) alkoxysilane or a partial hydrolytic condensate thereof; 0.1-10 pts.wt. of (E) a titanium chelate catalyst; and 0.01-5 pts.wt. of (F) a tackifier. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
