  • Patent number: 6562180
    Abstract: The invention concerns a cross-linkable adhesive silicone composition, and the use of said composition for bonding various substrates, comprising: a polyorganosiloxane (POS) with Si-Vi(polydimethylsiloxane &agr;,&ohgr;-dj-Vi) units; a crosslinking POS with SiH units; a platinum catalyst; an adherence promoter comprising vinyltrimethoxysilane, 3-glycidoxy-propyltrimethoxysilane and buryl titanate; and optionally a filler and/or a cross linkage inhibitor and/or an unsaturated POS resin such as MMviDDviQ or MDviQ. The invention aims at providing a highly adhesive glue having, before setting, a low viscosity adapted for easy application on the substrates to be bonded. The invention achieves this by providing a cross-linkable adhesive silicone composition as defined above and characterised in that it has a peeling force Fp≧0.25 N/mm. a viscosity &eegr;≧50.103mPa's at 25°, a tear resistance Rd≧6/mm (ASTM-624A) and a Shore hardness A≧35.

  • Patent number: 5783311
    Abstract: CVE polyorganosiloxane compositions crosslinkable into silicone elastomeric state, well suited for the protective coating of a wide variety of substrates and supports, notably vehicular airbags, are improvedly adhered thereto by including in said CVE silicone compositions an adhesiveness promoter comprising (1) at least one alkoxylated organosilane containing, per molecule, at least one C.sub.2 -C.sub.6 alkenyl radical, (2) at least one organosilicon compound containing at least one epoxy radical, and (3) at least one chelate of metal M and/or a metal alkoxide having the formula: M(OJ).sub.n, wherein n is the valency of M, J is a linear or branched C.sub.1 -C.sub.8 alkyl radical, and M is selected from among Ti, Zr, Ge, Li, Mn, Fe, Al and Mg.
