ABSTRACT:
The invention relates to foundry binder systems which contain modified polyisocyanates. The modified polyisocyanates are prepared by reacting a polyisocyanate with a triglyceride of ricinoleic acid. These modified polyisocyanates a phenolic resole resin are mixed with a foundry aggregate to form a foundry mix which is shaped and cured with an amine curing catalyst.
