Abstract
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).
