Title: Organic hydroxy silicates utilized as curing agents for polyurethane prepolymers

Abstract: Liquid isocyanate-terminated polyurethane prepolymers are cured by mixing them with 10% to 200% by weight, based on the weight of the prepolymer, of an organic hydroxy silicate compound or their condensation product. The cured material may be non-porous elastomeric products or fine cellular products.
