FREE RADICALLY CURED COLD-BOX BINDERS CONTAINING AN ALKYL SILICATE

摘要

This invention relates to foundry binder systems, which will cure in the presence of sulfer dioxide and a free radical initiator, comprising (a) an epoxy resin; (b) an acrylate; (c) an alkyl silicate; and (d) an effective amount of a free radical initiator. The foundry binder systems are used for making foundry mixes. The foundry mixes are used to make foundry shapes (such as cores and molds) which are used to make metal castings, particularly ferrous castings.
