Abstract
A solvent-free liquid silicone rubber composition comprising (A) an organopolysiloxane containing at least two alkenyl groups, (B) an organohydrogenpolysiloxane having at least two hydrogen atoms each attached to a silicon atom, (C) wet silica having a BET specific surface area of 150-250 m2/g, a mean particle size of 0.01-20 μm, and a sodium ion content of up to 0.35 wt % Na2O, (D) an adhesive agent, and (E) a platinum group catalyst is useful for coating onto air bag base fabric to form a thin film having good infiltration, strong adhesion and minimized surface tack.
