Process for treating a flexible bi-constituent self-demolding silicone membrane used as a counterform particularly for resin transfer molding. The membrane is coated with a thin layer of at least one monoconstituent silicone which is a polysiloxane cross-linkable at ambient temperature in the presence of the moisture in air. The polysiloxane corresponds to the formula (I):in which:the substituents R<3>, R<4>, and R<5 >are selected from alkyl or aryl radicals,R<6 >represents an alkyloxy group, an alkenyloxy group, an alcanoyloxy group, an amino group, a ketiminoxy group, an amido group, an aminoxy group. |
