Abstract:
1. Process for the production of an assembly comprising several silicone elements crosslinked by the polyaddition of ≡Si—H units onto ≡Si-alkenyl units, said elements adhering firmly to one another, comprising the following essential steps: (I) forming a silicone element (i) with a liquid silicone preparation (i) comprising: (II) crosslinking the liquid silicone preparation (i) formed in step (I), the composition of this preparation and the crosslinking conditions being chosen in such a way that the crosslinked silicone element (i) has a surface density SD of unreacted, residual alkenyl groups, per nm (III) optionally repeating steps (I) and (II) n times (n=positive integer) to give n elements (i) that adhere to one another, (IV) forming a silicone element (ii) by bringing the crosslinked silicone element or last crosslinked silicone element (i) into contact with a liquid silicone preparation (ii) comprising: (V) crosslinking the liquid silicone preparation (ii) formed in step (IV) to give the crosslinked silicone element (ii) that adheres to the element or last element (i).
