Abstract
A binding agent comprising 95 to 50% by weight of a furan resin, 5 to 50% by weight of lignin from the Organosolv process and organic and/or inorganic acid curing agents useful for the production of curable molding compositions, high temperature-stable molding substances and refractory products, especially casting cores and casting molds.
Claims18
