  • Patent number: 8317220
    Abstract: A curable coating composition that exhibits improved cure and adhesion to various substrates, especially synthetic textiles used in the manufacture of air bags, comprises a composition curable by a hydrosilylation reaction, an acryloxy functional alkoxysilane or a methacryloxy functional alkoxysilane, an alkenyl functional silanol terminated organopolysiloxane, and an epoxy functional alkoxysilane. The curable coating composition is especially useful for application to synthetic textiles such as automotive air bags.

  • Publication number: 20120289110
    Abstract: Silicone rubber compositions for coating air bags, used for safety purposes to protect occupants of vehicles such as automobiles are described together with air bag fabrics coated with the composition and to air bags made from the coated fabric. The compositions are silicone rubber coating compositions which cure by hydrosilylation comprising an organopolysiloxane (A) having aliphatically unsaturated hydrocarbon or hydrocarbonoxy substituents, an organosilicon crosslinker having at least 3 silicon-bonded hydrogen atoms, a catalyst able to promote the reaction of the aliphatically unsaturated hydrocarbon or hydrocarbonoxy substituents with Si—H groups and a silica reinforcing filler, wherein the silica filler is pre-treated with 2% to 60% by weight based on the weight of the silica filler of an oligomeric organopolysiloxane containing Si-bonded methyl and vinyl groups and silanol end groups.

  • Patent number: 8058190
    Abstract: A curable coating composition that exhibits improved cure and adhesion to various substrates, especially synthetic textiles used in the manufacture of air bags, comprises a composition curable by a hydrosilylation reaction, and includes a silicone resin, a hydrosilylation reaction inhibitor; and an adhesion promoting additive which comprises (i) an acryloxy functional alkoxysilane or a methacryloxy functional alkoxysilane, (ii) an alkenylsilanol, (iii) an organotitanium compound, (iv) a metal chelate compound, and (v) an epoxy functional alkoxysilane. A filler and a cyclic alkenyl group bearing polysiloxane can also be included in the curable coating composition. The curable coating composition is especially useful for application to synthetic textiles such as automotive air bags.

  • Publication number: 20110076479
    Abstract: A silicone composition and process are used to form a non-sewn seam in an airbag for use in vehicle applications. The airbag has a seam made from a silicone material prepared from the silicone composition. The silicone material and the process for forming the airbag seam minimize the need for sewn seams.

  • Patent number: 5939477
    Abstract: A pressure sensitive adhesive composition which contains a mixture of a silicate resin, a polyorganosiloxane fluid, and a polyisobutylene polymer having at least one functionalized silicon containing moiety. One advantage of the present invention is that it provides a silicone pressure sensitive adhesive composition that has a reduced propensity for cold flow relative to many current silicone pressure sensitive adhesives.

  • Patent number: 5658975
    Abstract: The instant invention pertains to a hot-melt pressure sensitive adhesive composition wherein the composition is comprised of a silicone pressure sensitive adhesive selected from the group consisting of a mixture of (i) a silicone resin and (ii) a silicone fluid and a condensed product of (i) and (ii); the silicone pressure sensitive adhesive exhibiting tackiness and adhesiveness; the silicone pressure sensitive adhesive being blended with (iii) from about 1 to 20 weight percent, based on the total weight of (i) and (ii), of a siloxylated polyether wax. The instant invention also encompasses method of using the composition, methods of making hot-melt silicone pressure sensitive adhesive-coated substrates, and devices made using the composition.
