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 8):
A mixture for curing by contacting with a tertiary amine or with a mixture of two or more tertiary amines, the mixture\n (a) being preparable by mixing the components of the two-component binder system as claimed in  claim 1 , and/or (b) comprising an ortho-fused phenolic resole having etherified and/or unetherified terminal methylol groups,\n a polyisocyanate having at least two isocyanate groups per molecule, \n a solvent and also, \n optionally, one or more additives, \n and the stoichiometric ratio of isocyanate groups in the polyisocyanate component to hydroxyl groups in the phenolic resin component being less than 1.2, and being preferably in the range from 0.5 to <1, more preferably in the range from 0.7 to 0.95, \n the mixture being free from compounds from the group of the alkyl silicates and alkyl silicate oligomers, \n and, based on the total mass of the mixture,\n the fraction of aromatic hydrocarbons is less than 27.6%, preferably less than 25%, and \n the fraction of rape seed methyl ester is less than 27.6%, preferably less than 25%.
