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): n n n in which: n the substituents R 3 , R 4 , and R 5 are selected from alkyl or aryl radicals, n R 6 represents an alkyloxy group, an alkenyloxy group, an alcanoyloxy group, an amino group, a ketiminoxy group, an amido group, an aminoxy group. |
