Zusammenfassung:	A process for modifying an expandable curing bladder for a tire, which bladder has a surface intended to come into contact with a tire casing is provided. The process comprises a step of applying to the surface a layer of a silicone rubber composition comprising a first liquid organopolysiloxane bearing chain-end alkenyl groups, a second liquid organohydropolysiloxane and a photoactivatable hydrosilylation catalyst, and a step of exposing the silicone rubber composition covering the surface to irradiation with ultraviolet-visible light.
