The invention is a pressure sensitive adhesive (PSA) composition, which is the ultraviolet radiation (UV) cured reaction product of a polyester-polyether-based urethane acrylate, one or more acrylate monomers, and a UV photosensitizer. The polyester-polyether-based urethane acrylate is the reaction product of between about 50 and 90 wt-% of a polyester diol having a molecular weight ranging from about 500 to 3200; between about 10 and 50 wt-% of a polyether polyol having a molecular weight ranging from about 1000 to 6000; between about 1 and 5 wt-% of a hydroxy-functional acrylate; and a polyisocyanate.

The subject invention relates to a foundry binder system which cures in the presence of a volatile amine curing catalyst comprising (a) an epoxy resin, (b) an acrylated organic polyisocyanate, (c) a reactive unsaturated acrylic monomer, acrylic polymer, or mixtures thereof, and (d) an oxidizing agent comprising a hydroperoxide. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes which are used to make metal castings.
