Fluorine-containing polysiloxane curable composition, rubber curable material or gel cured product coated with the cured product of the composition, electric / electronic component, and optical semiconductor device having the coated rubber curable or gel curable material, and method for reducing surface stickiness of rubber curable material or gel cured article

摘要

To provide a fluorine-containing polysiloxane curable composition for forming a coating film with low tackiness, and a rubber cured product or a gel cured product coated with a cured product of the above composition.SOLUTION: The fluorine-containing polysiloxane curable composition comprises: (A) a cyclic organopolysiloxane that has, in one molecule, a monovalent perfluoroalkyl group or a monovalent perfluorooxyalkyl group bonded to a silicon atom constituting a siloxane via a divalent hydrocarbon group, and a monovalent aliphatic unsaturated hydrocarbon group directly bonded to a silicon atom constituting a siloxane; (B) a cyclic organopolysiloxane that has, in one molecule, a hydrogen atom directly bonded to a silicon atom constituting a siloxane, and a monovalent perfluoroalkyl group or a monovalent perfluorooxyalkyl group bonded to a silicon atom constituting a siloxane via a divalent hydrocarbon group; and (C) a platinum group metal-based catalyst.SELECTED DRAWING: Figure 1
