ACRYLATE-FREE BINDERS CONTAINING AN EPOXY RESIN AND AN ALKYLSILICATE |
摘要 |
This invention relates to foundry binder systems, which cure in the presence of sulfur dioxide and an oxidizing agent, comprising (a) an epoxy resin; (b) an alkyl silicate; (c) an ester of a fatty acid, (d) an effective amount of a oxidizing agent, and (e) no ethylenically unsaturated monomer or polymer. Th e 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.
