    摘要： Provided is a silicone adhesive composition and an application thereof, that has a viscosity that enables coating even with a small amount of solvent content, has excellent curability due to hydrosilylation reaction, cures, has sufficient adhesive strength for practical use, and has excellent mechanical strength and elongation of the adhesive layer after curing, and can form a pressure-sensitive adhesive layer having sufficient adhesive strength for practical use. The adhesive composition comprises: (A) a chain-like organopolysiloxane having at least two aliphatic unsaturated carbon-carbon bond-containing groups only at the terminals of the molecular chain; (B) a straight-chain organohydrogenpolysiloxane having silicon-bonded hydrogen atoms only at both terminals of the molecular chain; (C) a resinous organopolysiloxane; and (D) an organopolysiloxane having at least one or more aliphatic unsaturated carbon-carbon bond-containing groups at locations other than the ends of the molecular chain, and having three or more aliphatic unsaturated carbon-carbon bond groups in the molecule.

    摘要： A liquid silicone resin composition is provided. The liquid silicone resin composition comprises (A) a polysiloxane, (B) a polyether alcohol compound, and optionally (C) an aminosilicon compound. The polysiloxane (A) comprises an MQ resin, which is dispersed in and optionally functionalized with the polyether alcohol compound (B), and which may also optionally have amino functionality. The liquid silicone resin composition comprises a tunable viscosity, which may range at 25° C. from 100 to 800,000 cps. A method of preparing the liquid silicone resin is also provided. The method comprises combining together a solid silicone resin and the polyether alcohol compound (B) to give a mixture comprising the polysiloxane (A) and the polyether alcohol compound (B), and liquefying the mixture, thereby preparing the liquid silicone resin composition. The method may optionally include the aminosilicon compound (C).
