Abstract: 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.
