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 &#x2550;Si&#x2014; [unsaturation]}; at least one polyorganosiloxane (POS) containing units &#x2550;Si&#x2014;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.

Single-component silicone elastomer compositions crosslinkable into self-adhesive state

Thermally-stable silicone elastomers are prepared from organopolysiloxane compositions by polyaddition, polycondensation or vulcanization reactions in the presence of peroxide; the thermal stability of the silicone elastomers is achieved by the inclusion of an additive derived from an iron (III) complex.

Thermally-stable crosslinked silicone elastomers

Gels having viscoelastic qualities, physical stability and adhesive properties, well suited for a wide variety of end applications, are prepared by crosslinking, by hydrosilylation, silicone compositions which contain:

Silicone compositions crosslinkable into adhesive gels

The field of the present invention relates to the field of batteries and of polymer electrolytes for batteries and more particularly to the field of lithium batteries. The invention relates to a composition which can be polymerized and/or crosslinked by polyaddition for a battery electrolyte comprising:

Crosslinkable composition for a battery electrolyte

A polyorganosiloxane composition that can be vulcanized at high temperature to a silicone elastomer, useful in the field of the manufacture of electrical wires or cables having an improved fire performance is provided. The composition includes a semi-reinforcing filler chosen from the group composed of:&#x2014;calcined kaolin powders, preferably that have undergone a chemical surface treatment;&#x2014;talc;&#x2014;calcium carbonate that may or may not have been surface-treated, for example with vinylsilanes, aminosilanes or (reactive or unreactive) silicone oils; and mixtures thereof.

Hot-vulcanizable polyorganosiloxane compositions useful particularly for manufacturing electrical cables or wires

The field of the present invention relates to the field of batteries and of polymer electrolytes for batteries and more particularly to the field of lithium batteries. The invention relates to a composition which can be polymerized and/or crosslinked by dehydrocondensation for a battery electrolyte comprising:

The invention relates to adhesive silicone elastomer compositions which can be crosslinked by polyaddition. The composition, crosslinkable by polyaddition (hydrosilylation), comprises: &#x3b1;/ at least one polyorganosiloxane (POS) bearing ethylenic and/or acetylenic unsaturations [POS with &#x2261;Si-(unsaturated) units]; &#x3b2;/ at least one polyorganosiloxane (POS) with &#x2261;Si&#x2014;H units; &#x3b3;/ a catalytic combination comprising &#x3b3;.1 at least one metallic catalyst (preferably platinum based), &#x3b3;.2 and at least one crosslinking inhibitor; &#x3b4;/ a filler; &#x3b5;/ at least one adhesion promoter; &#x3c1;/ at least one POS resin; &#x3bb;/ at least one thermal resistance agent; and &#x3c6;/ optionally at least one other functional additive. Methods of making and using the subject composition are also described.

Single-component adhesive silicone elastomer composition which can be crosslinked by polyaddition

The invention concerns a silicone composition crosslinkable into elastomer by hydrosilylation, in the presence of carbene-based metal catalysts. The invention aims at providing a composition of that type, stable over long periods at room temperature (one day to several months), without loss of its characteristic of being heat-curable by hydrosilylation and without generating secondary isomerization or coloring reactions. The invention is characterised in that the composition comprises: a polyorganovinylsiloxane(polydimethyl)(methylvinyl) siloxane; a polyorganohydrogenosiloxane; a platinum catalyst formed by a complex of formula C3 and optionally an acetylene crosslinking inhibitor, optionally a siliceous filler. The invention also concerns novel hydrosilylation catalysts of the metal complex type of formula C3 above. The life span of the potted single-constituent compositions of the invention is significantly increased
