Silicone coated base material and air bag base material

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 .mu.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 .mu.m selected from the group consisting of carbon, NiO.sub.2, FeO, FeO.sub.2, Fe.sub.2 O.sub.3, Fe.sub.3 O.sub.4, CoO.sub.2, CeO.sub.2, and TiO.sub.2, and
• (E) a catalytic amount of a platinum catalyst.
