Document Type and Number:
Japanese Patent JP7444234
Kind Code:
B2
Abstract:
A curable fluoropolyether adhesive composition which comprises, each in a specific amount, (A) a straight-chain polyfluoro compound having two or more alkenyl groups per molecule and having a perfluoropolyether structure in the main chain, (B) a fluorine-containing organohydrogen siloxane having, per molecule, a perfluoroalkyl group, a perfluorooxyalkyl group, a perfluoroalkylene group or a perfluorooxyalkylene group and two or more SiH groups, and not having an epoxy group or an alkoxy group directly bonded to a silicon atom, (C) a platinum-group metal catalyst, and (D) a cyclic organopolysiloxane having, per molecule, an SiH group and an epoxy group and/or a trialkoxysilyl group bonded to a silicon atom via a divalent hydrocarbon group optionally containing an oxygen atom, and not having fluorine in molecule, and a cured product of which having a thickness of 2 mm shows a transmittance to light with a wavelength of 500 nm of 80% or higher. This curable fluoropolyether adhesive composition is capable of providing a cured product having good light transmittance and high adhesiveness to glass materials.
