Adhesion method of photocurable fluoropolyether-based elastomer composition

Japanese Patent JP6344256

B2

PROBLEM TO BE SOLVED: To provide a method for sticking a photocurable fluoropolyether-based elastomer composition to a substrate, which composition allows a cured product obtained when the composition is irradiated with light to have excellent characteristics.SOLUTION: The method for sticking the photocurable fluoropolyether-based elastomer composition to the substrate comprises the steps of: irradiating the photocurable fluoropolyether-based elastomer composition containing the following components with specified light to obtain the cured product; further heating the cured product; and sticking the heated cured product to the substrate. The component (A) is a straight-chain polyfluoro compound having two or more alkenyl groups in one molecule thereof and a fluoropolyether structure in a main chain thereof. The component (B) is fluorine-containing organo hydrogen siloxane having two or more hydrogen atoms, each of which is bonded directly to a silicon atom, in one molecule thereof. The component (C) is a photoactive hydrosilylation reaction catalyst. The component (D) is hydrophobic silica powder. The component (E) is organosiloxane having one or more hydrogen atoms, each of which is bonded directly to the silicon atom, one or more epoxy groups and/or one or more trialkoxysilyl groups, each of which is bonded to the silicon atom through the carbon atom or the carbon atom and the oxygen atom.SELECTED DRAWING: None
