Abstract:
1. An addition reaction-curable silicone pressure-sensitive adhesive composition, comprising: (A) a polydiorganosiloxane comprising a linear polydiorganosiloxane (A1) and a linear polydiorganosiloxane (A2) having a mass ratio of (A1)/(A2) within a range from 90/10 to 10/90, in an amount of 20 to 80 parts by mass, wherein (B) a polyorganosiloxane comprising R (C) a polyorganohydrogensiloxane comprising three or more SiH groups within each molecule, in an amount such that a molar ratio of SiH groups within the polyorganohydrogensiloxane (C) relative to alkenyl groups within the polydiorganosiloxane (A) is within a range from 0.5 to 20; (D) a reaction retarder, in an amount within a range from 0 to 8.0 parts by mass per 100 parts by mass of a combination of the polydiorganosiloxane (A) and the polyorganosiloxane (B); (E) a platinum group metal-based catalyst, in an amount sufficient to provide a mass of the platinum group metal equivalent to 1 to 5,000 ppm relative to a combined mass of the polydiorganosiloxane (A) and the polyorganosiloxane (B); and (F) a metal compound represented by a formula MY wherein the polyorganosiloxane (B) is condensed with the linear polydiorganosiloxane (A2).
