Silicone coated base material and air bag base material
First Claim
1. A silicone coated base material comprising a base material selected from the group consisting of polyamide fibers, polyester fibers, woven and non-woven fabrics thereof, thermoplastic elastomers, and polyurethane sheets and a coating formed on at least a portion of said base material to a thickness of 5 to 20 μ
- m, said coating being the cured product of a silicone coating composition comprising(A) 100 parts by weight of an organo-polysiloxane having at least two alkenyl groups each directly bonded to a silicon atom in a molecule,(B) an organohydrogenpolysiloxane having at least two hydrogen atoms each bonded to a silicon atom in a molecule, in a sufficient amount to give 0.5 to 4 silicon-bonded hydrogen atoms per alkenyl group in component (A),(C) 0.1 to 10 parts by weight of an organic silicon compound having in a molecule at least one hydrogen atom bonded to a silicon atom and at least one epoxy and/or trialkoxysilyl group bonded to a silicon atom through a carbon atom directly bonded to the silicon atom,(D) 0.1 to 100 parts by weight of at least one powder having a mean particle size of up to 20 μ
m selected from the group consisting of carbon, NiO2, FeO, FeO2, Fe2 O3, Fe3 O4, CoO2, CeO2, and TiO2, and(E) a catalytic amount of a platinum catalyst.

Abstract
A material in the form of polyamide fibers, polyester fibers, woven and non--woven fabric thereof, thermoplastic elastomer, and polyurethane sheet is coated with a silicone coating composition to a thickness of 5 to 20 μm, obtaining a silicone coated base material. The silicone coating composition contains (A) an organopolysiloxane having at least two alkenyl groups, (B) an organohydrogenpolysiloxane having at least two hydrogen atoms, (C) an organic silicon compound having at least one hydrogen atom and at least one epoxy and/or trialkoxy-silyl group, (D) a carbon, NiO2, FeO, FeO2, Fe2 O3, Fe3 O4, CoO2, CeO2 or TiO2 powder having a mean particle size of up to 20 μm, and (E) a platinum catalyst. The silicone coated base material is flame resistant and fully acceptable in practical use even though the silicone coating is as thin as 5 to 20 μm, namely less than about one-half of the conventional coating thickness.
