Abstract
A method of producing a layer of a UV-cured silicone rubber composition on a substrate surface, including applying a primer composition to the substrate surface and hardening the primer composition followed by applying a UV-curable silicone rubber composition, and UV-curing the curable silicone rubber composition. 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 the silicone primer composition.
