Abstract
A coated fabric includes a reinforcement, a first coating disposed on the reinforcement, and a second coating disposed on the first coating. The first coating includes perfluoropolymer. The second coating includes perfluoropolymer and a silicone polymer in an amount in a range of 2 wt % to 30 wt %.
Claims20
A coated fabric comprising:
- a reinforcement material;
- and
- a coating overlying the reinforcement material, the coating comprising perfluoropolymer and a silicone polymer in an amount in a range of 2 wt % to 30 wt %;
- wherein the coated fabric has a permeability of not greater than 0.001 cuin/min.
1 more element
A sheet material comprising a blend of perfluoropolymer and silicone polymer, the blend comprising the silicone polymer in an amount in a range of 2 wt % to 30 wt %.
A method of forming a coated fabric, the method comprising:
- dispensing a fabric;
- applying a first emulsion coating to the fabric, the first emulsion comprising a perfluoropolymer;
- fusing the first emulsion coating to form a first layer;
- applying a second emulsion coating on the first emulsion coating, the second emulsion coating comprising a blend of perfluoropolymer and silicone polymer in an amount in a range of 2 wt % to 30 wt %;
- and
- fusing the second emulsion coating to form a second layer.
