Abstract

Self-adhesive addition-crosslinking silicone compositions, contain two adhesion promoters, a first, multinuclear aromatic compound containing at least one moiety of aliphatic unsaturation, and a low viscosity organopolysiloxane having at least one terminal, silicon-bonded hydrogen. The addition curable materials exhibit strong adhesion to substrates, even substrates which have exhibited problematic adhesion to silicone elastomers in the past.
