Zusammenfassung:A process for the preparation of cold-hardening mixtures, preferably for the foundry, which comprises preparation of monomer-oligomer binding agents in the performance of the ester exchange reaction of silicone-organic compounds with furfuryl alcohol in the presence of the ester exchange catalyst by introduction of reagents with ethyl alcohol distillation followed by formation of cold-hardening mixtures.
