Disclosed is a base fabric for automobile air bags having excellent flexibility to ensure compact folding of the air bag and high flame retardancy for safety in hazard, which consists of a woven fabric web and a rubbery coating layer formed thereon from a silicone-based coating composition in the form of an aqueous emulsion comprising: (a) 100 parts by weight of an organopolysiloxane represented by the general formula X-[-SiR12-O-]m-[-SiZ2-O-]n-SiR12-X, in which R1 is a monovalent hydrocarbon group having 1 to 20 carbon atoms, Z is R1, OR2 or -(-O-SiR12-)k-OR2, R2 being a hydrogen atom or R1 and k being a positive integer not exceeding 1000, X is R1 or OR2, m is a positive integer of 100 to 10,000 and n is 0 or a positive integer not exceeding 1,000 and which contains at least two OR2 groups in a molecule; (b) from 0.5 to 50 parts by weight of an organohydrogen polysiloxane having, in a molecule, at least three silicon-bonded hydrogen atoms; (c) from 0.5 to 100 parts by weight of a finely divided silica filler or a powder of an polyorganosilsesquioxane; (d) from 0.1 to 20 parts by weight of an alkoxy silane compound having, in a molecule, at least one amido group and at least one carboxyl group or a partial hydrolysis-condensation product thereof: (e) from 0.1 to 20 parts by weight of an alkoxy silane compound having, in a molecule, at least one epoxy or amino group or a partial hydrolysis-condensation product thereof; and (f) from 0.01 to 10 parts by weight of a curing catalyst for the composition. |
