摘要： A curable organopolysiloxane composition containing a fluoroalkyl group is disclosed. The composition comprises: (A) an organopolysiloxane containing a fluoroalkyl group, having at least two alkenyl groups in a molecule, where 10 mol % or more of all substitution groups on the silicon atoms is a fluoroalkyl group, and the average degree of polymerization is less than 150; (B) an organohydrogen polysiloxane having at least two silicon-bonded hydrogen atoms in a molecule at an amount where the silicon-bonded hydrogen atoms in the component is 0.1 to 1.0 mol with regard to a total of 1 mol of the alkenyl groups in component (A); (C) an effective amount of a hydrosilylation reaction catalyst; and optionally, (D) a solvent. The composition generally has a high dielectric constant and favorable transparency. A cured product and applications of the composition and the cured product thereof are also disclosed.

摘要： This disclosure provides a highly dielectric film that is formed of a fluoroalkyl-group-containing organopolysiloxane cured product and that has a high dielectric constant and is substantially flat and uniform in a width direction of the film, usages thereof and a manufacturing method therefor. There is provided the highly dielectric film formed of a fluoroalkyl-group-containing organopolysiloxane cured product, in which in a width direction of the film, a difference between a thickness at an end of the film and a thickness at a center of the film is 5.0% or less, and the thickness at the center of the film falls within a range of 50 to 1000 μm. Such a film may be provided with a primer layer and a planarization layer, and the film may be obtained by means of rolling and may also be obtained by means of curing performed between separators provided with a separation layer.

摘要： Provided is a laminate having, on a substrate, a gel layer which is excellent in heat resistance, has low elastic modulus, low stress and is excellent in stress buffering properties and flexibility, is soft and excellent in holding property of electronic components before curing, and after curing, the gel layer is changed to a hard cured layer which is higher in shape retention and excellent in mold releasability than before curing, and a method for manufacturing the same. Also provided is a method for manufacturing an electronic component in which use of the laminate makes it difficult to cause problems such as deposits of silicone gel or a cured product thereof to a substrate or an electronic component, and makes it difficult to cause problems of defects or defective products of the electronic component. The laminate includes a curing reactive silicone gel layer on at least one type of substrate.

摘要： Provided are a novel composite material in which a fluoropolymer and a fluorine-containing organopolysiloxane are dispersed in a mutually inseparable state, a method for producing the same, use of the same, and a precursor composition. The fluoropolymer-fluorine-containing organopolysiloxane composite material comprises: (A) one or more fluoropolymers selected from the group comprising polyvinylidene fluoride and polyvinylidene fluoride copolymers; (B) an organopolysiloxane crosslinking reaction product having a fluorine atom-containing organic group, obtained by subjecting to a crosslinking reaction a reactive organopolysiloxane having a fluorine atom-containing organic group and one or more reactive functional groups in the molecule capable of crosslinking between molecules by the reaction of these reactive functional groups; and optionally (X) fillers and/or other additives besides component (A) and component (B). Components (A) and (B) are included such that the mass ratio ((A)/(B)) of component (A) and component (B) is in the range of from 99/1 to 60/40.
