Abstract:
A foundry mix includes a major amount of a foundry aggregate and an effective binding amount of a binder system. The binder system cures in the presence of sulfur dioxide and a free radical initiator. The binder system may include (1) 10 to 70 parts by weight of an epoxy novolac resin; (2) 0.5 to 10 parts by weight of resorcinol; (3) 20 to 70 parts by weight of a monomeric or polymeric acrylate; and (4) an effective amount of a free radical initiator. Notably, (1), (2), (3) and (4) are separate components or mixed with another of said components, provided (4) is not mixed with (3), where said parts by weight are based upon 100 parts of the binder system.

Claim (Index 15):
A method of casting a metal article comprising:\n fabricating a foundry shape by introducing a foundry mix into a pattern to form the foundry shape, and curing said shape with gaseous sulfur dioxide;\n wherein the foundry mix includes:\n (a) 20 to 70 parts by weight of an epoxy novolac resin; \n (b) 20 to 65 parts by weight of a multifunctional acrylate; \n (c) 0.5 to 10 parts by weight of resorcinol; \n (d) an effective of amount of a free radical initiator, \n \n provided (a) is not mixed with (d) prior to mixing the foundry mix, and where said parts by weight are based upon 100 parts of the foundry mix; \n pouring said metal while in the liquid state into said foundry shape; allowing said metal to cool and solidify; and separating the cast article.
