Abstract
Binding agent compositions for inorganic fillers or oxides containing a curable binder such as a hardenable resin, and a ureido-functional organosilicon compound as described. Foundry sand compositions including binding agent compositions as described, sand and a catalyst for the hardenable resin. Shaped products comprising inorganic oxide particles, e.g., sand, a binding agent composition as described and catalyst for the hardenable resin wherein the hardenable resin is in its hardened form. Novel ureido-functional organosilicon compounds having two hydrolyzable or hydroxy groups to the molecule and at least one ureido-functional group in which the ureido group is connected to silicon by means of a group containing at least five carbon atoms.
