Abstract:
1. An adhesive composition comprising (A) 100 parts by weight of a linear polyfluoro compound having a perfluoropolyether structure in its main chain and having at least two alkenyl groups per molecule, (B) a fluorinated organohydrogensiloxane having at least two silicon-bonded hydrogen atoms (i.e., SiH groups) per molecule, in an amount to provide 0.5 to 3.0 moles of SiH groups per mole of alkenyl groups on component (A), C) a platinum group metal-based hydrosilylation catalyst in an amount to provide 0.1 to 500 ppm of platinum group metal, (D) 0.5 to 30 parts by weight of hydrophobic silica powder, (E) 0.05 to 3.0 parts by weight of a fluorinated acetylene alcohol having the general formula (2) or (3): wherein Rf 2 is a perfluoroalkyl group of 3 to 100 carbon atoms, which may be separated by an ether bond and which may be branched, Q is a divalent hydrocarbon group of 1 to 6 carbon atoms, R 3 , R 4 and R 5 are each independently an alkyl group of 1 to 4 carbon atoms, and T is a divalent organic group of 1 to 20 carbon atoms, and (F) 0.1 to 10 parts by weight of an organosiloxane containing at least one silicon-bonded hydrogen atom and at least one member selected from the group consisting of epoxy groups and trialkoxysilyl groups bonded to a silicon atom via a carbon atom or via carbon and oxygen atoms per molecule.
