The general field of the invention is that of silicone coating compositions, in particular those of two-component or multi-component type, that can be crosslinked by polyaddition or hydrosilylation reactions to produce a support coated by a silicone elastomer as a thin layer. These silicone compositions, when they are crosslinked, are suitable, inter alia, as coatings, for example for the protection or mechanical reinforcement of various textile substrates such as for example fibrous, woven, knitted or nonwoven supports. The targeted objective is to provide a silicone elastomer coating composition that can be crosslinked by polyaddition reactions and that is useful in particular for applications in the field of inflatable safety bags for vehicles, or airbags, having, after crosslinking, optimum properties in terms of adhesion, thinness, lightness and crease and abrasion resistance, but also good mechanical properties. This silicone coating composition should also be easy to use and to apply.

A process for modifying a silicone elastomeric-based surface of an article where the coefficient of friction (COF) of the silicone elastomeric-based surface is generally reduced by at least 5% is disclosed. The process comprises subjecting the silicone elastomeric-based surface of the article to vacuum ultraviolet (UV) radiation.

The lubricant (A) includes a sulfur-containing ester (A3). The amount of the lubricant (A) ranges from 50 to 90 wt %, the amount of the ester (B) ranges from 1 to 20 wt % and the amount of the sulfur-containing ester (A3) ranges from 5 to 20 wt %, to a nonvolatile component of the finish.

The present invention addresses the problem of providing a cloth which, when used as an air bag main body cloth, does not undergo the damage caused by a high-temperature gas generated from an inflater, and therefore has high heat resistance and is suitable for an air bag. The means for solving the problem is a coated cloth for an air bag, which is produced by applying an elastomer resin layer on at least one surface of a three-dimensional woven fabric in an amount of 50 to 500 g/m.sup.2 per one surface, said coated cloth being characterized by having void spaces formed therein, wherein the void content in the coated cloth is 15 to 60%. Preferably, the coated cloth is used in applications in which the coated cloth is attached onto the periphery of an inflater connection opening in an air bag.

A polyvinyl alcohol (PVA)-based airbag base fabric aqueous coating material is described. A blocked polyisocyanate component (B-NCO) and liquid polyol are added to polyvinyl alcohol as a cross-linkage improver and a plasticizer, respectively. The B-NCO is composed of or based on a medium-molecular-weight form as a polyether-modified prepolymer, and used concurrently with a low-molecular-weight form in a small amount. The base fabric coating material is applied on one or both of the sides of a cloth of the base fabric and heated. The acquired coating film is a water-insoluble coat and the coating has excellent heat and moisture resistance (hot water resistance) and flexibility.

The present invention provides a coating fabric for airbags where an elastomer is coated to at least one side of textile constituted from synthetic fiber filament, which is characterized in that the coating weight of the resin is as small as 10 to 20 g/m.sup.2 and an average resin thickness of the head top in the textile surface is 4.0 m to 12.0 m in both directions of warp and weft and that the average value of burning speed measured according to FMVSS 302 is not more than 60 mm/min in both directions of warp and weft and the maximum value thereof is not more than 1.2-fold to the average value in both directions of warp and weft.
