| titleOfInvention | Urethane curable organic binder for mold, foundry sand composition and mold obtained using the same |
| abstract | An object of the present invention is to provide a urethane-curing organic binder that can advantageously provide a mold with improved moisture absorption resistance, and effectively suppresses the reduction in mold strength due to standing after molding. There is also provided a urethane-curable organic binder for molds that can be molded, and a foundry sand composition capable of imparting excellent mold characteristics using such a urethane-curable organic binder, and its Provided is a mold having excellent characteristics which is molded using a foundry sand composition. A urethane curable organic binder used for molding a urethane mold, which is composed of two liquids, a liquid A mainly composed of a polyol compound and a liquid B mainly composed of a polyisocyanate compound. The liquid A contained a reaction product of a basic silane compound and hydrofluoric acid as a constituent component, and the water content was 0.1 to 15 wt%. [Selection figure] None |
