Document Type and Number:
Japanese Patent JPH09503963
Kind Code:
A
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 derivatives. 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.
