Abstract: A method for activating silicone rubber surfaces comprising steps of: i) swelling at least the surface of the silicone rubber matrix with a silicone rubber swelling solvent; ii) treating the silicone rubber matrix during or after the swelling with a solution comprising at least a reactive silane, the reactive silane comprising: a) at least one Si—C bond and; b) at least one hydrolytically labile bond linked to at least one of the Si atoms present in the reactive silane and; c) at least one functional group F1 connected via a Si—C bond to the same or an other Si atom present in the reactive silane, the functional group comprising electrophilic and/or nucleophilic moieties, and/or at least one functional group F2 connected via a Si—C bond to the same or an other Si atom present in the reactive silane comprising moieties which become electrophilic or nucleophilic moieties by a mechanism selected from the group consisting of ring opening of a cyclic structure, hydrolysis, displacement or by a migration reaction; iii) drying and/or heat treating of the treated silicone rubber matrix.
