Composite materials contain a silicone addition crosslinkable silicone elastomer composition comprising an organopolysiloxane having aliphatic unsaturation, an Si&#x2014;H functional cyclic organopolysiloxane, a hydrosilylation catalyst, together with specific adhesion promoters, applied to a substrate material.

Self-adhesive silicone elastomers

Base compositions for addition-crosslinking silicone compositions are continuously produced by, in a first stage, homogeneously mixing and kneading organopolysiloxanes and flowable prehydrophobized oxidic reinforcing fillers in a continuous kneading machine with kneading chambers arranged alongside one another. In a second, downstream, stage of the process, the compositions produced in the first stage are subjected to aftertreatment in a mixing apparatus in which the compositions have been subjected to a mixing procedure with introduction of shear force.
