... years, a number of resins have been developed as binders for sand, primarily for making cores, although they are also used as molds. These binder systems generally fall into one of the following categories: no-bake, cold box, protein, hot/warm box, and shell (Croning). In these processes, sand...

... for smaller castings. In heat-cured binder systems, the resin hardens when heated, as in the case of the shell process or furan warm box. On the other hand, cold box systems use a vapor form of catalyst. Since World War II, many chemical binder systems have been introduced and used for aluminum castings...

... or blown into a mold or core box, these binders are cured by introducing into the sand a vaporized liquid or gaseous catalyst at room temperature. No external heat is required. Currently, there are two gas-cured organic binder systems widely in use: the phenolic urethane-amine system and the furan-SO 2...

These properties, in addition to lower hot strength, make the round sand grains particularly suitable for coremaking. Angular grains, because...
