Abstract
A liquid silicone rubber coating composition comprising (A) an organopolysiloxane containing at least two silicon-bonded alkenyl radicals, (B) an organohydrogenpolysiloxane containing at least two SiH radicals, (C) an addition reaction catalyst, optionally (D) finely divided silica, (E) triallyl isocyanurate, (F) an organosilicon compound containing an epoxy radical and a silicon-bonded alkoxy radical, and (G) a titanium or zirconium compound is coated on a surface of an airbag base fabric and cured to form a rubber coating layer thereon. The composition is suited for curtain airbags.
Claims3
A liquid silicone rubber coating composition to be cured to form a silicone rubber coating layer on at least one surface of the substrate of textile fabric of curtain airbags, comprising
- (A) 100 parts by weight of an organopolysiloxane containing at least two silicon-bonded alkenyl radicals per molecule,
- (B) an organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms per molecule, in a sufficient amount to provide 1 to 10 silicon-bonded hydrogen atoms per silicon-bonded alkenyl radical in component (A),
- (C) a catalytic amount of an addition reaction catalyst,
- (D) 0 to 50 parts by weight of finely divided silica having a specific surface area of at least 50 m2/g,
- (E) 0.1 to 1 part by weight of triallyl isocyanurate,
- (F) 0.1 to 10 parts by weight of an organosilicon compound containing an epoxy radical and a silicon-bonded alkoxy radical per molecule, and
- (G) 0.1 to 5 parts by weight of a titanium or zirconium compound.
