Abstract: 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 constricting 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 mainer 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.
Abstract: Disclosed are polyhedral organosilicon compounds which are possible to be polymerized and can form a film excellent in adhesiveness to a substrate, having a high hardness, a high transparency and having water and oil repellency, and comprise organofluoro groups or both of organofluoro groups and reactive functional groups, the compounds being soluble in an organic solvent and stable.
Organosilicon compounds which have perfluoroalkyl groups or both perfluoroalkyl groups and reactive functional groups and which have a polyhedral structure have the following formulas of (I), (II) and (III):
[Rf1—X1—(CH2)a—SiO1.5]m (I)
[Rf1—X1—(CH2)a—SiO1.5]m[Rf2—(X2)c—(CH2)b—SiO1.5]n (II)
[Rf1—X1—(CH2)a—SiO1.5]m[R—(X2)c—(CH2)b—SiO1.
