摘要:
A monomeric foundry binder comprising furfuryl alcohol and resorcinol is disclosed. The binder is substantially anhydrous, generates no nitrogen, is free of formaldehyde odor both in fabrication of the binder and in production of the sand shapes, and in pouring operations. It provides strengths which are better than those normally achieved with polymeric furfuryl alcohol-containing resins, and provides for quicker strip times.
