Abstract
A novel organofunctional silane for use in binding agent compositions employed in foundry sands and the cores and molds made therefrom. The novel organofunctional silane is characterized in that it contains at least one sterically hindered hydrocarbon group and has attached to the silicon atom a nitrogen containing group via a carbon-silicon bond.
