PURPOSE:To provide the titled composition having excellent autohesive properties, by compounding a polymer having a main chain composed of a polyether and having hydrolyzale and crosslinkable silicon group, a silicone-modified epoxy resin, and a curing catalyst, at specfic ratios. CONSTITUTION:The objective composition is prepared by mixing and kneading (A) 100pts.wt. of a polymer having a main chain composed essentially of a polyether (such as polyoxypropylene having a molecular weight of preferably 300-20,00) and having hydrolyzable and crosslinkable silicon group (e.g. silyl group bonded with alkoxy group, etc.) at the chain terminals, (B) 0.01-20pts.wt. of a silicone-modified epoxy resin (a product obtained by the reaction of a compound having two or more epoxy functional groups in the molecule with a silicone compound having a functional group reactive with epoxy group), (C) 0- 10pts.wt. of a curing catalyst (e.g. tin octylate), and if necessary (D) a filler, etc. USE:The composition is useful as an elastic sealant, paint, adhesive, etc. for the bonding of glass, metal, stone, especially mortar, etc. |
