Abstract:
1. An air bag having a rubber coating layer comprising a cured product of a liquid silicone rubber coating composition with a viscosity at 25° C. of 10,000 to 100,000 mPa·s, consisting of: (A) 100 parts by mass of a combination of substantially straight chain alkenyl group-containing organopolysiloxanes consisting of (A-1) a substantially straight chain diorganopolysiloxane containing alkenyl groups only at both molecular chain terminals, in which each of said molecular chain terminals is blocked, independently, with a group represented by a formula R (A-2) a substantially straight chain copolymer of a diorganosiloxane and an alkenylorganosiloxane containing an average of at least two alkenyl groups, only at non-terminal molecular chain positions, within each molecule, in which both molecular chain terminals are blocked with groups represented by a formula R (B) an organohydrogenpolysiloxane containing an average of at least two hydrogen atoms bonded to silicon atoms within each molecule, in sufficient quantity to provide from 1 to 7 mols of hydrogen atoms bonded to silicon atoms for each 1 mol of alkenyl groups bonded to silicon atoms within said composition, said organohydrogenpolysiloxane comprising: (B-1) an organohydrogenpolysiloxane in which both molecular chain terminals are blocked with groups represented by a formula R (B-2) a copolymer of a diorganosiloxane and an organohydrogensiloxane, in which each molecular chain terminal is blocked, independently, with a group represented by a formula R (C) an effective quantity of an addition reaction catalyst, and (D) 0.1 to 10 parts by mass of an adhesion improver.
