    摘要: A binder resin composition, a curing agent composition, a caking additive composition, a kit, a casting mold composition and a process for manufacturing a casting mold are disclosed, wherein a metallic compound containing a metallic element belonging to Group IB to VIII of the Periodic Table is utilized. The compositions are useful for the production of a sand mold for casting, having an excellent strength, from reclaimed sand, in a self-hardening or gas hardening mold process. The casting mold according to the present invention, which is manufactured in the presence of a metallic compound containing a metallic element belonging to Group IB to VIII of the Perioidic Table has excellent strength.
