PURPOSE: To obtain a two-part type curable composition, excellent in adhesion, etc., even without carrying out the primer treatment and useful as a repairing material or a covering material for intermediate coating of a polyolefin molded part by combining a principal agent containing specific additive resins added to a specified reactive resin with an organic peroxide as the curing agent. CONSTITUTION: This composition is obtained by combining a principal agent containing (B) at least one of a styrene-based copolymer (preferably a styrene- isoprene-styrene copolymer, a styrene-butadiene-styrene copolymer or a styrene- ethylene-butadiene-styrene copolymer) and a polyalkylene resin (preferably an amorphous polypropylene resin) as additive resins added to (A) at least one of an unsaturated polyester resin, a vinyl ester resin and a liquid polybutadiene copolymer as a reactive resin with (C) an organic peroxide as the curing agent. Furthermore, the component (B) in an amount of 50-200 pts.wt. based on 100 pts.wt. component (A) is preferably blended therewith and the component (C) in an amount of 0.1-5wt.% based on the principal agent is blended therewith. |
