Abstract In typical metal foundry applications, sand casting is still the most used technology. The related binder plays a
very important role as its performances can directly influence the quality of castings. Among many binders, glues
of animal origin have attracted much attention in recent years due to their reduced environmental impact. However, they display some drawbacks such as the tendency to coagulate easily at room temperature and a relatively
low strength. In this study, a novel gas-hardening casting binder was prepared using an animal glue and anhydrous potassium carbonate as a hydrolyzing agent to avoid undesired agglomeration. Moreover, sodium pyrophosphate… More >
