ABSTRACT:
The invention relates to foundry binder systems which use modified polyisocyanates. The modified polyisocyanates are prepared by reacting a polyisocyanate with an aliphatic alcohol having one active hydrogen atom. These modified polyisocyanates, along with a phenolic resole resin, are added to a foundry aggregate to form a foundry mix which is shaped and cured with a gaseous amine curing catalyst.
