Abstract:
A process for treating a flexible self-demolding two-package silicone membrane, comprising a membrane coated with a 0.1-0.5 mm thick layer of at least one-package silicone, wherein said one-package silicone is a polysiloxane cross-linkable at ambient temperature in the presence of moisture, and said membrane is constituted by a material obtained by cross-linking a linear polymer constituted by recurrent siloxane units carrying alkyl or aryl substituents, said polymer carrying at one of its ends a group comprising a vinyl function which is capable of reacting via a radical route, and at the other end a group that is non-reactive under conditions of polymerization via a radical route, a so-called blocking group.
