Title:
POLYURETHANE-FORMING BINDER SYSTEMS CONTAINING 2,2'-DIPYRIDYL, 1,10-PHENANTHROLINE, AND THEIR SUBSTITUTED ALKYL DERIVATIVES
Document Type and Number:
WIPO Patent Application WO1995003903
Kind Code:
A3
Abstract:
This invention relates to polyurethane-forming foundry binder systems which contain a nitrogen-containing aromatic compound selected from the group consisting of 2,2'-dipyridyl, 1,10-phenanthroline, and their substituted alkyl derivates. The foundry binder systems are particularly useful for making foundry mixes used in the cold-box fabrication process for making foundry shapes. However, the binders systems can also be used to hold foundry shapes, such as molds and cores, together in an assembly. 00000
