Abstract:
1. A hot-melt silicone adhesive comprising: (A) an organopolysiloxane resin with a softening point in the range of 40 to 250° C. that contains in one molecule at least one aryl group and contains neither a silicon-bonded alkoxy group nor a silicon-bonded hydrogen atom; (B) an organopolysiloxane that at 25° C. is liquid or is in the state of a crude rubber, which contains in one molecule at least two alkenyl groups and at least one aryl group and which contains neither a silicon-bonded alkoxy group nor a silicon-bonded hydrogen atom, wherein component (B) is added in an amount of 10 to 500 parts by mass per 100 parts by mass of component (A); (C) a composition selected from a mixture of (i) an organopolysiloxane that contains in one molecule at least two silicon-bonded hydrogen atoms and does not contain a silicon-bonded alkoxy group and (ii) an organic silicon compound that contains in one molecule at least one silicon-bonded alkoxy group; or (iii) an organopolysiloxane that contains in one molecule at least two silicon-bonded hydrogen atoms and at least one silicon-bonded alkoxy group; (D) a hydrosilylation catalyst; and (E) a hydrosilylation-reaction inhibitor.
