Abstract

The invention relates to self-adhesive addition-crosslinking silicone compositions which comprises(A) diorganopolysiloxanes, (B) organohydrogenpolysiloxanes containing less than 20 SiH bonded hydrogen atoms and less than 12% aryl groups, (C) organosilicon compounds having epoxy groups and hydrolyzable groups and (D) a hydrosilylation catalyst. The compositions are transparent to translucent, exhibit good compositional comparability, and cure to form strongly adhesive elastomers with good physical properties.
