<P>PROBLEM TO BE SOLVED: To provide an adhesive agent composition for a mold used in self-hardening molding, which can improve hardening rate and mold strength of the mold, and has good storage stability of the adhesive agent composition, and to provide a mold-manufacturing method using the same. <P>SOLUTION: An adhesive agent composition for a mold used in self-hardening molding contains a furan resin and an ionic compound, wherein the ionic compound contains one or more anions selected from the group consisting of hydrogen sulfide ions, sulfurous acid ions, pyrosulfurous acid ions, thiosulfurous acid ions, thionic acid ions, and dithionous acid ions, the anion content is between 0.006 and 0.60 pt.wt. per 100 pts.wt. of furan resin effective content, and pH at 25°C is 6 or lower. <P>COPYRIGHT: (C)2013,JPO&INPIT |
