ABSTRACT:
A process for producing a molded product by reacting an organic isocyanate component with an isocyanate reactive component. If the isocyanate component is based on a prepolymer of an isocyanate and a fatty acid ester, then the isocyanate reactive component must contain a fatty acid. Alternatively, if the isocyanate component contains a fatty acid, then the isocyanate reactive component must contain a zinc carboxylate. The system will release from bare steel.
