Zusammenfassung:	The subject invention relates to a two component foundry binder system that cures in the presence of an amine curing catalyst, preferably a volatile amine. On e component of the binder system comprises (1) an effective amount of an oxidizing agent, a nd preferably (2) an epoxy component. The other component comprises (1) an organic polyisocyanate, (2) and (2) an acrylate monomer having at least two acrylate functional grou ps selected from the group consisting of ketal, acetal and formal acrylate monomers. The foundry binders are used for making foundry mixes. The foundry mixes are used to mak e foundry shapes, such as molds and cores, which are used to make metal castings.
