Abstract
The invention relates to adhesive silicone elastomer compositions which can be crosslinked by polyaddition. The composition, crosslinkable by polyaddition (hydrosilylation), comprises: α/ at least one polyorganosiloxane (POS) bearing ethylenic and/or acetylenic unsaturations [POS with ≡Si-(unsaturated) units]; β/ at least one polyorganosiloxane (POS) with ≡Si—H units; γ/ a catalytic combination comprising γ.1 at least one metallic catalyst (preferably platinum based), γ.2 and at least one crosslinking inhibitor; δ/ a filler; ε/ at least one adhesion promoter; ρ/ at least one POS resin; λ/ at least one thermal resistance agent; and φ/ optionally at least one other functional additive. Methods of making and using the subject composition are also described.
