Abstract: A curable silicone composition is disclosed. The curable silicone composition comprises: (A) a linear organopolysiloxane having at least two alkenyl groups and at least one aryl group in a molecule; (B) a branched organopolysiloxane represented by the average unit formula; (C) an organosiloxane having at least two silicon atom-bonded hydrogen atoms in a molecule; and (D) a hydrosilylation reaction catalyst. The curable silicone composition forms a cured product having good mechanical properties and good retention of transparency under conditions of high temperature.

Abstract: A silicone resin is disclosed. The silicone resin is free from carbon atoms. A method of preparing the resin is additionally disclosed. This method comprises reacting a silane compound and a precursor compound, thereby preparing the silicone resin. A composition including the silicon resin and a vehicle is further disclosed. A method of preparing a film with the composition is also disclosed. This method comprises applying the composition including the silicone resin and the vehicle to a substrate to form a layer. This method also includes heating the layer to give the film.

Abstract: A curable silicone composition is disclosed. The curable silicone composition comprises: (A) a silicone resin consisting essentially of R3SiO1/2 siloxane units and SiO4/2 siloxane units, wherein each R is the same or different, and independently selected from halogen-substituted or unsubstituted monovalent hydrocarbon groups free of aliphatic unsaturated bonds; (B) an organopolysiloxane having at least two alkenyl groups per molecule and free of SiO4/2 siloxane units in the organopolysiloxane; (C) an organosiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; and (D) a hydrosilylation catalyst. The curable silicone composition can be cured to form a cured product having a high tensile strength in addition to a low modulus.

Abstract: A silicone release coating composition and method for its preparation and use are described. A release coating prepared by curing the silicone release coating composition has high immediate release force (>50 g/in). A release liner including the release coating is suitable for use as a transfer liner in processes for making composites articles, such as aircraft parts.
