Liquid silicone rubber coating composition, curtain airbag, and its production method

A method for producing a curtain airbag comprising the steps of coating a liquid silicone rubber coating composition comprising

• (A) 100 parts by weight of an organopolysiloxane having at least 2 alkenyl groups bonded to silicon atoms per molecule;
• (B) an organohydrogenpolysiloxane having at least 2 hydrogen atoms bonded to silicon atoms per molecule, at an amount such that 1 to 10 hydrogen atoms bonded to silicon atoms in the component (B) are present in relation to one alkenyl group bonded to the silicon atom in the component (A);
• (C) an effective amount of an addition reaction catalyst;
• (D) 0 to 50 parts by weight of a fine powder silica having a specific surface area of at least 50 m2/g;
• (E) 0.1 to 10 parts by weight of an organic compound represented by the following general formula (1):
• wherein R1 is independently a substituted or unsubstituted monovalent hydrocarbon group and n is an integer of 2 to 10;
• (F) 0.1 to 10 parts by weight of an organosilicon compound having an epoxy group and an alkoxy group bonded to a silicon atom in the molecule;
• and
• (G) 0.1 to 5 parts by weight of at least one member selected from titanium compounds and zirconium compounds on at least one surface of a substrate comprising a fiber cloth, and
• curing the coating composition to form a silicone rubber coating layer composed of the cured product of the coating composition on the at least one surface of the substrate.
