    • A silicone composition and the uses thereof, particularly as a coating on an airbag for protecting the occupant of a vehicle in the event of a collision, are disclosed. The aim is to provide a silicone composition suitable for coating onto the inner surface of the airbag while significantly reducing the weight of the resulting coating layer to form a protective coating having enhanced high-temperature, mechanical and substrate-adhesion properties. Said aim is achieved in that the composition is free of reinforcing mineral fillers and consists of a mixture of (1) at least one polyorganosiloxane with alkenyl groups bound to the silicon; (2) at least one polyorganosiloxane with hydrogen atoms bound to the silicon; (3) a cross-linking catalyst; (4) an adhesion promoter comprising (4.1) at least one alkoxylated organosilane, (4.2) at least one epoxy-functional organosilicon compound, and (4.3) at least one metal chelate and/or metal alkoxide wherein the metal is selected from the group which consists of Ti, Zr, Ge, Li, Mn, Fe, Al and Mg; (5) at least one polyorganosiloxane resin; and (6) optionally at least one cross-linking inhibitor.
