Patent attributes
Provided is a liquid silicone rubber coating agent composition, including: (A) an organopolysiloxane containing at least one alkenyl group bonded to a silicon atom within each molecule, (B) a straight-chain organohydrogenpolysiloxane containing a single silicon atom-bonded hydrogen atom only at each molecular chain terminal, with a viscosity at 25° C. within a range from 0.001 to 1.0 Pa·s, (C) an organohydrogenpolysiloxane containing at least three silicon atom-bonded hydrogen atoms within each molecule, with a viscosity at 25° C. within a range from 0.001 to 10 Pa·s, (D) an addition reaction catalyst, (E) a finely powdered silica with a BET specific surface area of at least 50 m2/g, and (F) an adhesion imparting agent. Also provided is a curtain air bag with a rubber coating layer formed by curing this composition. The coating agent composition is useful for a curtain air bag that is capable of suppressing leakage of the inflator gas and exhibits excellent sustainability of the inflation period, and is also useful in the production of such an air bag.
