Abstract
(EN)
A composition for use in modifying the adhesion properties of silicone rubber compositions is described. The composition comprises alkoxy silanes, such as alkoxy silanes further comprising additional chemical functional groups such as epoxides, esters, and anhydrides; diffusion promoters that are completely or partially immiscible in the silicone rubber composition being modified; and compounds that can balance the hydride content of the silicone rubber compositions being modified. Modified curable silicone rubber compositions and methods of modifying the adhesive properties of silicone rubber compositions are also described. In particular, use of the presently disclosed compositions can provide modified silicone rubber compositions having selective adhesion for surfaces comprising thermoplastic and thermoset polymers as compared to metal surfaces.

L'invention concerne une composition destinée à être utilisée pour modifier les propriétés d'adhérence de compositions de caoutchouc silicone. La composition comprend des alcoxysilanes, tels que des alcoxysilanes comprenant en outre des groupes fonctionnels chimiques additionnels tels que des époxydes, des esters, et des anhydrides ; des promoteurs de diffusion qui sont complètement ou partiellement immiscibles dans la composition de caoutchouc silicone soumise à la modification ; et des composés qui peuvent équilibrer la teneur en hydrures des compositions de caoutchouc silicone soumises à la modification. L'invention concerne également des compositions de caoutchouc silicone durcissables modifiées et des procédés de modification des propriétés adhésives de compositions de caoutchouc silicone. En particulier, l'utilisation des compositions décrites dans la présente invention peut fournir des compositions de caoutchouc silicone modifiées ayant une adhérence sélective à des surfaces comprenant des polymères thermoplastiques et thermodurcissables, par comparaison avec des surfaces métalliques.
