Abstract

Siliconized release film for the production of polymer moldings from fiber composites using a mold, which comprises a support film which is capable of vacuum deep drawing at room temperature and a coating which can be applied in liquid form and consists, optionally after removal of any solvent, of more than 90 atom % of silicon, carbon and/or oxygen, more than 45 atom % of carbon and more than 20 atom % of silicon, in each case based on the total coating and measured by XPS, characterized in that the coating has been crosslinked by means of condensation reactions, addition reactions or radiation.
