Abstract
Phenolic resin-polyisocyanate binder systems comprising aqueous emulsions of a phenolic resin and a liquid polyisocyanate and a tertiary amine or metal ion curing agent can be made and used free of organic solvents, thereby providing improved environmental conditions. These binders are useful as foundry core and mold binders in both cold box and no bake operations.
