1. A process for fabricating an airbag comprises:
- 1) applying a first bead of a first polyorganosiloxane composition to an airbag component,2) applying a second bead of a second polyorganosiloxane composition to the same airbag component or a different airbag component,3) contacting the first polyorganosiloxane composition and the second polyorganosiloxane composition between two airbag components,4) compressing the two airbag components to form a seam at least 0.5 mm thick;
where the seam comprises a first material made from the first composition and a second material made from the second composition, where the first material and the second material differ in hardness, modulus, or both; and
where the first material is located toward the interior of the airbag, the second material is located toward the exterior of the airbag, and the first material and the second material contact each other;
thereby eliminating the need for sewing one or more of seams in the airbag.
