September 15, 2022
Provided are an addition-curable liquid silicone rubber composition having exceptional adhesiveness and adhesive durability in a silicone rubber coating layer with respect to an airbag fabric, and an airbag. An addition-curable liquid silicone rubber composition for airbags having, as essential components: (A) an organopolysiloxane having a weight-average degree of polymerization of 100-2,000 and containing two or more silicon-atom-bonded alkenyl groups per molecule; (B) an organohydrogenpolysiloxane containing at least two silicon-atom-bonded hydrogen atoms per molecule; (C) a silica fine powder having a BET specific surface area of 50 m/g or higher; (D) a catalyst for a hydrosilylation reaction; (E) an organic compound including at least one functional group selected from alkenyl groups, alkoxysilyl groups, and hydrosilyl groups, and at least one isocyanate group, per molecule; and (F) a condensation catalyst selected from organic titanium compounds, organic zirconium compounds, and organic aluminum compounds.
