Abstract
The present invention relates to a process for the production of storable thermosetting polyurethane-polyurea compositions wherein a storable isocyanate component stabilized by a surface coating and a polyol and/or polyamine component are separately prepared. A one-component polyurethane-polyurea reactive mixture is formed by mixing just before the intended use the separate components under mild shear forces at a temperature below the thickening temperature of the final reactive mixture.
