Abstract (en)

[origin: WO2009016199A2] The present invention relates to a high-performance silicone elastomer composition that is adhesive and that can be crosslinked at high temperature for the assembly of silicone-based substrates, both by platinum and peroxide catalysis, and that may lend itself to a strip conformation. The composition comprises at least one gum, one catalyst and one adhesion promoter of polyorganohydrogensiloxane type, the nature and the amount of said adhesion promoter having been chosen so that Si-H groups are in excess following the reaction for crosslinking the composition, so as to obtain a potential surface density of covalent Si- bonds with the silicone substrate to be bonded of at least one covalent Si- bond per 60 nm2.
