摘要: A curable organopolysiloxane composition comprising: (A) a mercapto group-containing organopolysiloxane; (B) a compound containing in a molecule at least two groups that are at least one type of functional groups selected from a group consisting of acryloyl groups, methacryloyl groups, and epoxy groups; and (C) an amine compound that does not have a N—H bond and/or a phosphine compound that does not have a P—H bond. The composition has favorable curability even at a relatively low temperature, and forms a cured film with excellent bonding with regard to an article to be coated.

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: 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.
