Provided is a two-component-curable polyurethane resin composition that has high compatibility, high adhesion, and a good low-dielectric-constant characteristic.

A two-component-curable polyurethane resin composition according to an embodiment includes a first component including a polyol and a terpene resin, and a second component including a polyisocyanate, wherein the polyol includes 30 mass % or more of a polybutadiene polyol and/or a hydrogenated polybutadiene polyol, and a content of the terpene resin relative to 100 parts by mass of the polyol is 1 to 60 parts by mass.

Molding material mixes that contain a polyurethane binder based on phenolic resins of the benzyl ether type and polyisocyanates are characterized by the inclusion of a polybutadiene derivative. In one case, the polybutadiene derivative has epoxide groups and hydroxyl groups. In another case, the polybutadiene derivative has succinic acid anhydride groups. Molds, cores and risers are produced using these molding material mixes. Inclusion of the polybutadiene derivatives results in a reduction of sand adhesions in the molding process.
