Abstract

The present invention is an addition-curable liquid silicone rubber composition for an airbag, including (A) a linear organopolysiloxane, (B) a powdery organopolysiloxane resin having a three-dimensional network structure, (C) organohydrogenpolysiloxane having two or more hydrosilyl groups per molecule, (D) a silica fine powder having a BET specific surface area of 50 m<2>/g or more, (E) a catalyst for a hydrosilylation reaction, (F) an organosilicon compound having an adhesiveness-imparting functional group, and (G) an expanded graphite powder having a median size of 0.1-50 µm, wherein, the component (c) is contained in such that the total sum of the hydrosilyl group in the composition is 1-10 mol per 1 mol of the total alkenyl groups bonded to a silicon atom in the composition. This can provide an addition-curable liquid silicone rubber composition for an airbag that is less prone to coating unevenness during coating and facilitates easy detection of defective products.
