Abstract
Abstract A curable composition. The composition comprises (A) 100 parts by weight of an oxyalkylene polymer having at least one silicon-containing group in which a hydroxyl group and/or hydrolyzable group is or are bonded to the silicon atom, said polymer being crosslinkable by formation of a siloxane bond, (B) from 0.1 to 20 parts by weight of a compound having one silanol group per molecule and/or a compound capable of forming a compound having one silanol group per molecule on reacting with moisture, and (C) from 0.1 to 20 parts by weight of a compound having an air oxidative curing unsaturated group. The composition provides a cured product which has low modulus and resistance to dust adhesion and on which an alkyd coating shows excellent coating properties.
