Beschreibung
Zusammenfassung:	The present invention provides an epoxy acrylate foundry binder compositio n having an epoxy resin component (Part 1) and an acrylate component (Part 2) containing about 1% to less than about 6% by weight of a borate ester. The epoxy acryla te binders of the present invention are useful in making foundry cores and molds in that t he addition of the borate ester increases hot strength of the binder system. Also provided is a cold-box process for making sand cores and molds using the epoxy acrylate binders cur ed by sulfur dioxide vapor.
