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 1):
A two-component binder system for use in the polyurethane cold box process consisting of a phenolic resin component and of a separate polyisocyanate component, where\n the phenolic resin component comprises an ortho-fused phenolic resole having etherified and/or unetherified terminal methylol groups, and a solvent, and optionally one or more additives and the polyisocyanate component comprises a polyisocyanate having at least two isocyanate groups per molecule and also optionally a solvent, and optionally one or more additives, the fraction of isocyanate groups in the polyisocyanate component being 90% or more, preferably 92% or more, more preferably 95% or more, very preferably 98% or more, based in each case on the total mass of the polyisocyanate component, 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 preferably in the range from 0.5 to <1, more preferably in the range from 0.7 to 0.95, where the phenolic resin component is free from compounds from the group of the alkyl silicates and alkyl silicate oligomers, and, based on the total mass of the phenolic resin component,\n the fraction of aromatic hydrocarbons is less than 39.43%, preferably less than 38%, \n and the fraction of rapeseed oil methyl ester is less than 39.43%, preferably less than 30%.
