ABSTRACT:
A curable composition is disclosed and comprises the following components.
(A) 100 parts by weight of a oxypropylene polymer having a polymer main chain containing a repeating unit represented by the following formula ##STR1## and having at least one group containing a silicon atom bonded to a hydroxyl group and/or a hydrolyzable group and capable of crosslinking by forming a siloxane bond, wherein Mw/Mn thereof is not more than 1.6 and the number average molecular weight is at least 6,000,
(B) from 1 to 200 parts by weight of a filler having a BET specific surface area of not higher than 10 m.sup.2 /g, and
(C) from 0.1 to 20 parts by weight of a curing catalyst, said composition containing substantially no plasticizer.
