An air bag coated with a cured organopolysiloxane composition, characterized in that the air bag is top coated with an antifriction coating comprising at least one solid lubricant dispersed in an organic polymer binder.

Coated fabric products

An inflatable vehicle safety device is provided that comprises an inflator, a fluid compartment, and a heat shield. The inflator is capable of providing an inflation fluid used to inflate the fluid compartment. The heat shield, which is located within the fluid compartment, comprises a fabric layer and a thermal barrier layer located adjacent to the fabric layer. The thermal barrier layer includes at least one layer of silicone elastomer and one or more silicone topcoats. The heat shield has a thermal resistance value of six seconds or more at 725&#xb0; C. when tested in a hot rod thermal resistivity test.

This relates to the coating of air bags, which are used for safety purposes to protect occupants of vehicles such as automobiles, and of air bag fabrics intended to be made into air bags. In particular the invention relates to the top coating of air bags and air bag fabrics which have been pre-coated with a cured organic resin coating composition. The top-coat is an anti-blocking coating composition comprising at least one solid lubricant dispersed in an organic polymer binder. A process for applying the top-coat is also described.

Provided is a liquid curable silicone rubber composition containing the following components of (A), (B), (C) and (D): (A) 100 parts by weight of an organopolysiloxane having one or more silicon atom-bonded alkenyl groups on average in one molecule, (B) (B-1) an organohydrogenpolysiloxane having at least three silicon atom-bonded hydrogen atoms in one molecule, wherein at least one of the hydrogen atoms is present as a siloxane unit represented by the formula of R1HSi02/2 (wherein R1 represents a non-substituted or substituted monovalent hydrocarbon group containing no aliphatic unsaturated bond) in the molecule and (B-2) a linear organohydrogenpolysiloxane having one silicon atom-bonded hydrogen atom only at each of both terminals of the molecular chain and having no aliphatic unsaturated bond(s) in a molecule, [provided that the blending amount of component (B-1) and component (B-2) is an amount such that the molar ratio of silicon atom-bonded hydrogen atoms contained in component (B-1) and component (B-2):alkenyl groups contained in component (A) ranges from (0.8:1.0) to (2.5:1.0), and the total number of silicon atom-bonded hydrogen atoms contained in component (B-2) is 70 to 100% of the total number of silicon atom-bonded hydrogen atoms contained in component (B-1) and component (B-2); provided that when the aforementioned numerical value is 100%, component (B) consists only of (B-2).] (C) a hydrosilylation reaction catalyst: an amount to cure the present composition, and (D) 0.1 to 50 parts by weight of a reinforcing silica fine powder. A coated woven fabric with a silicone rubber-coated layer formed of a cured product of this liquid curable silicone rubber composition is suitable as a coated woven fabric for use in airbags.
