A curable perfluoropolyether gel composition is provided. The composition comprises (A) a straight chain fluorine-containing polymer represented by the following formula (1): n n n n n n n n n n (B) a polyfluoromonoalkenyl compound containing one alkenyl group per molecule and having a perfluoropolyether structure in its backbone, (C) an organosilicon compound containing at least two hydrogen atoms bonded to the silicon atom per molecule, and (D) a hydrosilylation catalyst. The composition can be produced into a cured product having excellent heat resistance, solvent resistance, chemical resistance, weatherability, releasability, water repellency, oil repellency, and the like as well as an improved acid resistance. |
