摘要： The present invention includes new compositions for making polyurethane and polyurethane foam compositions. These compositions comprise the reaction product of an isocyanate A-Side and a B-Side comprising: (i) a polyol having a molecular weight of about 1000 g/mol or more, and having an average functionality of 2.0 or greater; (ii) a polyol having a Tg of about −80° C. or less, and having a molecular weight of about 1000 g/mol or more, and having an average functionality of 2.0 or greater; and(iii) a polyhydric alcohol having a molecular weight of about 90 g/mol or more, and having an average functionality of 3.0 or more. In the case of polyurethane foam compositions, the system also comprises water. The invention also includes processes for making the polyurethane and polyurethane foam compositions, as well as methods of adhering the same to cosmetic layers comprising thermoplastic, acrylic, and gel coat materials. The invention also includes articles made from these reinforced cosmetic layers.
