Patent number: 6468929Abstract: This invention relates to a new adhesive coating composition, particularly for use on airbag fabrics, which is composed of a crosslinked blend of a polyalkyl- or polyphenylsiloxane with vinyl functionality and a copolymer of ethylene and methyl acrylate. This coating provides excellent adhesive properties to the coated fabric, in that it restricts the movement, when put under stress, of the yarns constructing that fabric, which are situated adjacent to seams in the fabric. This reduces the effect known in the trade as combing. Fabric treated with this material in the manner described herein, requires a marked increase in the amount of force required for this yarn movement. This distortion of the fabric can be detrimental in an automotive airbag, in that, it may result in the loss of inflating air, and under extreme conditions may result in a seam failure.Type: GrantFiled: June 26, 2001Date of Patent: October 22, 2002Assignee: Milliken & CompanyInventor: Richard Henry Parker

Patent number: 6271280Abstract: Intermediate compositions comprising ethynylorgano polyorganosiloxanes are prepared by hydrosilylation of an olefinic hydroxy compound followed by reaction with a propargyl halide, or by hydrosilylation of a diethynyl compound. The intermediate compositions may be oxidatively coupled to form poly(conjugated diacetylenic)polyorganosiloxanes. The latter may be cured thermally or by radiation to form cured compositions useful as release coatings or conformal coatings.Type: GrantFiled: April 19, 2000Date of Patent: August 7, 2001Assignee: General Electric CompanyInventors: Sylvie Louise Boileau, Anna Elzbieta Kowalewska, Laurent Bouteiller, Matthew David Butts, Slawomir Rubinsztajn
