Abstract:
A description is given of a two-component binder system for use in the polyurethane cold box process, a mixture for curing by contacting with a tertiary amine, a method for producing a feeder, a foundry mold or a foundry core, and also feeders, foundry molds and foundry cores producible by this method, and the use of a two-component binder system of the invention or of a mixture of the invention for binding a mold raw material or a mixture of mold raw materials in the polyurethane cold box process.

Claim (Index 10):
A method for producing an article from the group consisting of feeders, foundry molds and foundry cores, comprising the following steps:\n providing or producing a mold raw material or a mixture of two or more mold raw materials, mixing the mold raw material or the mixture of two or more mold raw materials with the phenolic resin component and the polyisocyanate component of a two-component binder system as claimed in  claim 1 , to form a molding mixture suitable for curing by contacting with a gaseous tertiary amine or with a mixture of two or more gaseous tertiary amines, the stoichiometric ratio of isocyanate groups in the polyisocyanate component to hydroxyl groups in the phenolic resin component in the molding mixture being less than 1.2, and preferably in the range from 0.5 to <1, more preferably in the range from 0.7 to 0.95 shaping the molding mixture, and contacting the shaped molding mixture with a gaseous tertiary amine or a mixture of two or more gaseous tertiary amines by the polyurethane cold box process, so that the shaped molding mixture cures to form the article from the group consisting of feeders, foundry molds and foundry cores, a total amount of gaseous tertiary amines being used which is less than 0.08 mol, preferably less than 0.05 mol, per mole of isocyanate groups.
