The cast polyurethane polymer of the invention withstands temperatures of 450.degree. F. (232.degree. C.) for 20 minutes without visual polymer degradation, whereas most other castable polyurethane systems degrade between 350.degree. F. and 375.degree. F., as a result of which heat-stability the polymer of the present invention is especially suitable for post finishing which involves the employment of higher temperatures, such as painting with thermosetting coatings, powder coating, and anodizing.
