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 &minus;80&deg; 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.

Low volatile reinforcing system

A thermosetting unsaturated polyester-polyurethane hybrid foam resin composition is made without significant blistering by using a 2-component catalyst system--one which initiates at room temperature and one which initiates at a temperature of at least 75.degree. C. and has a one-hour half-life temperature of at least 90.degree. C.; the composition has a room temperature stability of at least thirty days.
