Method of producing a layer of a UV-cured silicone rubber composition on a substrate surface, comprising applying a primer composition to the substrate surface and hardening said primer composition followed by applying a UV-curable silicone rubber composition, and UV-curing said curable silicone rubber composition, characterized in that at least one UV-sensitive crosslinking catalyst selected from compounds which initiate and promote curing of UV-curable silicone rubber compositions is added to the silicone primer composition in any desired sequence before, during or after hardening of said silicone primer composition.
