For a coating process was preparing polyurethane surface and methods for their preparation

The invention relates to a method for producing a polyurethane molded article comprising the steps of providing a reaction mixture that can react to form polyurethane, providing a mold for molding the polyurethane molded article with a low surface energy and a specific additive for the reaction mixture. The method further includes the steps of mixing the additive with the reaction mixture and curing the mixture in the mold. Here, the additive that is a good delamination possible without release agent must be used ensured.
