PHENOLIC RESIN COMPOSITION FOR SHELL MOLDING, RESIN COATED SAND FOR SHELL MOLDING, AND SHELL MOLD FORMED OF THE SAME

摘要

Provided are a phenolic resin composition for shell molding that has low thermal expansion properties and high flexibility, a resin coated sand for shell molding obtained by using the same, and a shell mold formed of the same. The phenolic resin composition for shell molding that is capable of exhibiting advantageous mold characteristic is obtained by a combination of a phenolic resin that is obtained by a reaction of a phenol, a naphthol, and an aldehyde, and a fatty acid amide.
