Abstract
A curable perfluoropolyether based gel composition is provided comprising (A) a linear fluorinated polymer containing at least two alkenyl groups, (B) a polyfluoromonoalkenyl compound containing one alkenyl group and having a perfluoropolyether structure in its backbone, (C) a cyclic organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms and at least one perfluoroalkyl group or perfluoropolyether structure-containing group, and (D) a hydrosilylation reaction catalyst. The composition cures into a gel having improved acid resistance as well as heat resistance, solvent resistance, chemical resistance, weatherability, parting property, and water/oil repellency.
