|
|  | Sefar can provide the following metallic surface modifications: |
| | | | |
.Surface modification
. | | .Metallic surface (Al,
.Cu, Ag, Au, Cu-Al, Ti)
. | | .Metallic surface (Ni)
. |
| | | | |
| .Technology | | sputtering / vapour deposition | | galvanic coating |
| | | | |
| .Properties | | coating thickness
10 - 100 nm, highly conductive, shielding, antistatic, antibacterial,
metallic look | | thick metallic coating (several µm) |
| | | | |
| .Advantages | | large range of metals and alloys possible, one or double sided coating possible | | high shielding effect and fabric stiffness |
| | | | |
| .Restrictions | | Au: high investment costs | | high process costs, only for fabrics with mesh openings
> 25 µm |
| | | | |
| .Typical applications | | mobile phones, lightening strike protection, medical, aerospace | | mobile phones, lightening strike protection |
