Zusammenfassung:	There is provided curable silicone elastomer compositions having enhanced adhesive properties with respect to a wide variety of substrates. The curable silicone elastomer compositions described herein are provided with a phenylmethylpolysiloxane based additive which comprises at least one, alternatively at least two Si-H groups per molecule and at least one, alternatively at least two anhydride functional groups per molecule. Said phenylmethylpolysiloxane based additives provide resulting elastomers with improved heat-humidity stabilization. L'invention concerne des compositions d'élastomère de silicone durcissables présentant des propriétés adhésives améliorées par rapport à une grande variété de substrats. Les compositions d'élastomère de silicone durcissables selon l'invention contiennent un additif à base de phénylméthylpolysiloxane comprenant au moins un, en variante au moins deux groupes Si-H par molécule, et au moins un, en variante au moins deux groupes fonctionnels anhydride par molécule. Lesdits additifs à base de phénylméthylpolysiloxane permettent d'obtenir des élastomères résultants dotés d'une stabilisation améliorée de chaleur-humidité.
