ABSTRACT:
A resin composition for a shell mold which reduces smoke generation upon molding of a casting mold and maintains a crumbility and a casting mold strength of a phenolic resin, and resin coated sand by the use thereof are provided. The resin composition for the shell mold includes the phenolic resin and an aromatic condensed phosphate ester. The phenolic resin is used as a binder of the resin coated sand used for producing a main mold and a core for shell mold casting of cast iron, cast steel, aluminum, and the like. The aromatic condensed phosphate ester is very effective as a crumbling agent for improving the crumbility of the casting mold after casting.
