The influence of sand binders in metalcasting operations is often underestimated, in particular their influence on process efficiency and casting quality.
The history of phenolic-urethane cold-box (PUCB) binders over the past 30+ years has seen many compositional variations as technological advances come, and in some cases go. Successful PUCB binders deliver optimal performance with the maximum number of positive attributes, without any properties that are obvious "show stoppers."
