Abstract

Process for preparing an aqueous mould release agent to be used in the manufacture of moulded polyurethane articles, which comprises first preparing an emulsion comprising a release active substance, water, an emulsifying agent and, optionally, a hydrocarbon, and then twofold homogenizing the emulsion. Using this process, a water-based mould release agent is obtained which provides the same demoulding performance than conventional solvent-based release agents. The disclosure also relates to the release agent obtainable with such process, to its use for preparing moulded polyurethane articles and to a process for preparing moulded polyurethane using this release agent.
