Abstract
The present invention provides siliceous-based polyurea compositions, obtainable by reacting isocyanates, alkali silicates and hydratable aluminosilicates. Moreover, the present invention provides a process for the manufacture of these compositions, comprising the steps of mixing a hydratable aluminosilicate with an aqueous silicate and reacting this mixture with a polyisocyanate and/or a polyisocyanate prepolymer, optionally in the presence of a polyol and/or with the inclusion of an inert filler. Finally, the present invention provides the use of these compositions in the fields of aviation, automotive assemblies, construction, consumer products, fire protection, furniture components, insulation, shipbuilding and/or windmill construction. The compositions obtainable according to the present invention are lightweight, high load bearing, flame retarding materials.
