Abstract

Single-component silicone elastomer compositions (SEA) are crosslinkable by polyaddition into self-adhesive state, contain at least one polyorganosiloxane (POS) including sites of ethylenic and/or acetylenic unsaturation {POS containing units ═Si— [unsaturation]}; at least one polyorganosiloxane (POS) containing units ═Si—H; a catalytic system including at least one metal catalyst and at least one crosslinking inhibitor; a filler; at least one adhesion promoter; optionally, at least one POS resin; optionally, at least one thermal resistance agent; and, optionally, at least one other functional additive, and are useful for gluing, assembling, sealing, e.g., joints, coatings, electrical, electronic and automobile engineering parts.
