ABSTRACT:
An addition-curable composition is comprised essentially of (A) a linear perfluoro compound containing at least two alkenyl groups per molecule and having a perfluoro structure in its backbone chain, (B) a linear perfluoro compound containing one alkenyl group per molecule and having a perfluoro structure in its backbone chain, (C) an organosilicon compound containing at least two hydrosilyl groups per molecule, and (D) a platinum family metal catalyst. A cured gel product obtained from the composition has a penetration of 1 to 200 (ASTM D-1403 using 1/4-scale cone). The composition can form a fluorine-containing cured gel product excellent in chemical resistance and solvent resistance, and low in moisture permeability.
