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 .mu.m, 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, 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 or TiO.sub.2 powder having a mean particle size of up to 20 .mu.m, 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 .mu.m, namely less than about one-half of the conventional coating thickness.
