Abstract (en)
[origin: FR2770220A1] Silicone compositions that can be crosslinked by hydrosilylation to form adhesive and shock absorbing gels comprise: polysiloxane (A), (B) and optionally (F); adhesion promoter (C); hollow organic microspheres (D); a hydrosilylation catalyst (E); and optionally a polysiloxane diluent. Polysiloxane (A) has terminal units of formula (R)2QSiO1/2 (I) and internal units of formula (R<1>)pQqSiO (II). In (I) and (II), R and R<1> = 1-6 C alkyl and/or optionally substituted aryl; Q = H or alkenyl, preferably vinyl; p = 1 or 2; q = 0 or 1; and p + q = 2. Polysiloxane (B) has terminal units of formula Qs(R<2>)tSiO1/2 (III) and internal units of formula Qu(R<3>)vSiO (IV). In (III) and (IV), R<2> and R<3> = R; s = 0-3; t = 0-3; s + t = 3; u = 0-2; v = 0-2, provided that v = 1 in at least one of the internal units; and u + v = 2. Polysiloxane diluent (F) has terminal units of formula (R<6>)3SiO1/2 (V) and internal units of formula (R<7>)2SiO (VI). In (V) and (VI), R<6> and R<7> = R.
