The invention relates to self-adhesive addition cross-linking silicone compositions, to a method for producing the same and to the silicone elastomers and composite materials produced therefrom. The surprisingly good adhesive properties of the silicone composition on particularly bisphenol A containing thermoplastics is obtained by the synergistic interaction of the adhesion-promoting components organohydrogenpolysiloxane (B), cyclic organohydrogenpolysiloxane (C) of the general formula (III) (SiHR7O)g (SiR8R9O)h and the adhesion promoter (D). The adhesion promoter (D) corresponds to general formula (IV), wherein R12 represents a hydrogen atom, a hydroxy group, a halogen atom, an alkyl, alkenyl, alkoxy, alkenyloxy or aryl group or a monovalent organic group that contains an alkenyl, alkoxy, glycidyl, carbonyl, carbonyloxy, silyloxy or alkoxysilyl group, at least one of the groups R12 representing (an) alkenyl group(s) or (an) alkenyl group(s) containing, monovalent, organic group, and X being selected from the following groups: -(R13-)C(-R13)-, -(0=)S(=0)-, -(0=)S-, -C(=0)-, -O-(CH3-)Si(- CH3) -0-, -(CH2)s- and -0- wherein R13 represents a hydrogen atom, a halogen atom or a substituted or unsubstituted alkyl, aryl, alkenyl or alkinyl group and s is a positive number from at least 2 and r is 0 or 1. |
