Abstract
A coated textile fabric that has utility for fabricating automobile airbags. A surface of the textile fabric is coated with first and second layers of polyorganosiloxane-based elastomeric material, the first layer being disposed between the textile surface and the second layer. The polyorganosiloxane-based material of the first layer exhibits an elongation-at-break of at least 400%. The polyorganosiloxane-based material of the second layer exhibits a tear-strength of at least 30 kN/m.
Claims22
A coated textile fabric comprising
- a. a textile fabric presenting at least one surface;
- b. said at least one surface being coated with first and second layers of polyorganosiloxane-based elastomeric material;
- c. said first layer being disposed between said at least one surface and said second layer;
- d. said polyorganosiloxane-based elastomeric material of said first layer exhibiting an elongation-at-break of at least 400%;
- e. said polyorganosiloxane-based elastomeric material of said second layer exhibiting a tear-strength of at least 30 kN/m.
A process for coating a textile fabric with comprises a first step of applying a first polyorganosiloxane-based elastomer-forming composition, which forms, upon curing, an elastomeric material having an elongation-at-break of at least 400%, to the textile fabric, a second step of applying a second polyorganosiloxane-based elastomer-forming composition, which, upon curing, forms an elastomeric material having a tear-strength of at least 30 kN/m, and a third step of causing the first and second polyorganosiloxane-based elastomer-forming composition to cure to form an elastomeric coating on the fabric.
