Abstract: 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.

Abstract: 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.
