Abstract: An adhesive bonding process can include: treating at least one region of the surface of a silicone part so as to increase the surface energy of the region treated; providing a double-sided adhesive tape comprising a support tape, a first layer of a pressure-sensitive adhesive (PSA) on a first face of the support tape and a second layer of a PSA on a second face of the support tape, applying a non-silicone-based structural adhesive to the treated region of the surface of the silicone part and/or to the first PSA layer, bringing the treated region of the surface of the silicone part into contact with the first PSA layer, and curing the non-silicone-based structural adhesive. An assemblage can be obtained by such a process.

Abstract: A self-adhesive seal assembly includes an elastomer seal (1), wrapped in a textile (2) and a double-sided adhesive tape (3) comprising a carrier tape (4), a first layer (5) of a pressure-sensitive adhesive (PSA) on one side of the carrier tape, a second layer (6) of a pressure-sensitive adhesive on the other side of the carrier tape, the elastomer seal (1) with the textile sheath (2) and the double-sided adhesive tape (3) irreversibly adhered to each another by means of a structural adhesive (7) forming a bonding seal. In an embodiment, also provided is a method for manufacturing such a self-adhesive seal assembly.

Abstract: A process for forming an elastic coating on a silicone support, includes: (a) treating at least one zone of the surface of a silicone part to increase the surface energy of the treated zone to a value greater than 30 mJ/m2, (b) depositing onto at least part of the treated zone a coating composition including: (i) a latex of a film-forming organic polymer bearing functions containing active hydrogen, (ii) an aqueous dispersion of a very high molecular weight polyorganosiloxane, and (iii) a crosslinking agent chosen from polyisocyanates, (c) heating or irradiating the layer of coating composition to react the crosslinking agent (iii) with the functions containing active hydrogen of the film-forming organic polymer (i) to form an elastic coating, components (i), (ii) and (iii) and the respective proportions thereof being chosen such that the support equipped with the coating can be elongated without the appearance of cracks in the coating.
