Patent ID: 8124690

Claim:
A curable composition comprising: (A) a polymer comprising a silicon group having a Si—F bond, wherein the main chain skeleton of the polymer (A) is at least one selected from the group consisting of a polyoxyalkylene based polymer, a saturated hydrocarbon based polymer, and a (meth)acrylic ester based polymer; and (B) a polymer having one or more silicon groups on average per molecule which are represented by the following general formula (2): —SiR 3 3-d Y d (2) (wherein, R 3 each independently represents a hydrocarbon group having 1 to 20 carbon atoms, or an organosiloxy group represented by R 4 3 SiO— (R 4 is each independently, a hydrocarbon group having 1 to 20 carbon atoms); further, Y is each independently, a hydroxyl group or a hydrolyzable group other than fluorine and d is any one of 1, 2, or 3), wherein said polymer (B) having one or more silicon groups has a number average molecular weight of 3,000 to 100,000.
