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 1):
A foundry binder system including:\n an aggregate; a first portion (Part One), wherein Part One includes an epoxy resin in a range from 25 to 70 parts by weight, and cumene hydroperoxide in a range from 10 to 40 parts by weight; a second portion (Part Two), wherein Part Two includes an epoxy novolac resin in a range from 10 to 40 parts by weight, polyhydroxy benzene in a range from 0.5 to 10 parts by weight, an acrylate in a range from 20 to 70 parts by weight; and wherein the aggregate, Part One, and Part Two are mixed together and exposed to sulfur dioxide to cure the aggregate into a foundry mold.
