<p>PURPOSE:To prepare an adhesive silicone compsn. exhibiting excellent adhesive properties even at a high temp. by compounding specific polysiloxanes, an organosilicon compd. or(and) an isocyanurate compd., and a Pt, Pd, or Rh cata lyst. CONSTITUTION:The subject compsn. comprises 100 pts.wt. polyorganosiloxane of formula I (wherein R<1> is alkenyl; R<2> is a monovalent hydrocarbon group contg. no aliph. unsatd. bond; and (a)+(b) is 1-3); a polyorganohydrogensiloxane of formula II (wherein R<3> is a monovalent hydrocarbon group; and (c)+(d) is 1-3) in such an amt. that the number of hydrogen atoms attached to silicon atoms is 0.3-5 based on one R<1> group in the polyorganosiloxane; 0.05-15 pts.wt. organosilicon compd. contg. a group having a (meth)acryloxyalkyl or epoxy group attached to a silicon atom and contg. a plurality of alkoxy groups, or(and) 0.005-10 pts.wt. isocyanurate compd. of formula III (wherein A is alkenyl, etc.); and a catalytic amt. of a Pt, Pd, or Rh compd.</p> |
