<p>A silicone composition for use as a pressure sensitive adhesive, comprising a mixture obtained by reacting (A) a polyorganosiloxane having at least two alkenyl groups per molecule with (B) a polyorganosiloxane having an R<SUP>1</SUP><SUB>3</SUB>SiO<SUB>0.5 </SUB>unit and a SiO<SUB>2 </SUB>unit, wherein R<SUP>1 </SUP>may be the same with or different from each other and is a monovalent hydrocarbon group having 1 to 10 carbon atoms, (C) a polyorganosiloxane having an SiH group, (D) a retarder and (E) a platinum group metal catalyst. A pressure sensitive adhesive tape made from the composition can be peeled off from an object without leaving adhesive residue even after aged at a temperature of 250° C. or higher.</p> |
