The present invention relates to a process for the production of polyurethane foam moldings having a compact surface skin and a density of at least 150 kg/m.sup.3 comprising foaming a polyurethane-forming starting mixture inside a mold. The starting mixture comprises organic blowing agents which correspond to one or both of the following general formulas:

Process for the production of moldings of polyurethane foams

A novel polyurethane prepared by reacting a) a specific polyol or specific polyol blend, b) an organic diamine, c) fillers, and d) a specific polyisocyanate is described. The invention also relates to the use of the polyurethane in the preparation of a composite structure wherein the polyurethane is applied to an adhesive coated ceramic enamel layer. The composites are eminently suitable for use in plumbing applications (e.g. as a bathtub).

The present invention is directed to a process of preparing a polyurethane structural support by spraying a specific polyurethane onto a substrate. The polyurethane is prepared by reacting a specific polyol blend, an organic diamine, and an isocyanate in the presence of a moisture absorbing material and a polysiloxane defoaming agent.
