Abstract

The invention relates to self-adhesive addition-crosslinking silicone compositions which contain the components(A) diorganopolysiloxanes having aliphatic unsaturation,(B) organohydrogenpolysiloxanes bearing compatability decreasing substituents,(C) compounds having at least one aliphatically unsaturated radical and at least one &bgr;-diketone function or &bgr;-keto ester function and(D) a hydrosilylation catalyst. The compositions are cost effective, and exhibit excellent adhesion to both metallic and non-metallic substrates while maintaining other desirable physical properties.
