ABSTRACT:
The invention relates to organomineral products of high strength obtainable by reacting a polyisocyanate in an aqueous alkali silicate solution in the presence of a catalyst prompting the trimerization of the polyisocyanate. In preparing them, the catalyst is used in an amount of 5.5 to 14.5 mmole per mole of NCO groups in the reaction mixture. The organomineral products of the invention are suitable as construction, coating, sealing or insulating materials or as putty or adhesives.
