Abstract
An adhesive silicone composition comprising a diorganopolysiloxane, an organohydrogenpolysiloxane, and a platinum catalyst is blended with an organohydrogenpolysiloxane having at least two hydrogen atoms each bonded to a silicon atom in a molecule and containing an aromatic ring-bearing hydrocarbon radical in an amount of at least 12 mol % of the entire monovalent organic radicals bonded to silicon atoms, or a compound containing at least one hydrogen atom bonded to a silicon atom in a molecule and having a radical of two benzene rings separated by --R.sup.13 R.sup.14 Si--, --R.sup.13 R.sup.14 SiO--, --OR.sup.13 R.sup.14 SiO-- or --R.sup.13 R.sup.14 SiOR.sup.13 R.sup.14 Si-- wherein R.sup.13 and R.sup.14 are a monovalent hydrocarbon radical. The composition firmly adheres to organic resins, but is readily releasable from metal molds.
