    摘要: The invention relates to the preparation of molded polyurethane parts having a lightfast polyurethane skin. The skin is formed by applying a reaction mixture comprising an organic polyisocyanate, a polyol, a chain extender, an aliphatic primary or secondary aliphatic diamine, and a catalyst, by a one-shot process in the absence of solvents, to the inside wall of the molding tool.The molded parts produced in accordance with this invention are used, for instance, in the automobile industry for the inside equipment of vehicles. Specifically, they may be used as cover plates for steering wheels and for lining doors. They may also be used for external equipment such as bumpers, headlight housings, and may be used in the electrical industry as housing elements.
