UV filter foil METOLIGHT SFLY5, yellow
Filter foil for application to window panes, blocks light below 470 nm.
METOLIGHT SFLY5 UV filter foil consists of a glass-clear, tear-resistant, dimensionally stable PET film, approx. 100 μm thick with an additional double-sided UV filter coating that blocks light below 470 nm. Thus, harmful UV light is absorbed.
Since only the light components below 470 nm are filtered out of daylight, only yellow-red colors remain visible to the human eye. The film is therefore ideal for coating windows in electronic labs, PCB-printing areas, chip- and solar panel manufacturing, UV curing ink- and resin manufacturing and all areas where UV curing materials are processed. Though such materials are mainly exposed from 360 to 380 nm libraries, most of them have a second sensivity peak between 400 and 480 nm. That is why a clear UV filter foil cannot be used for UV-safe lighting. In some cases it is recommended to use the amber UV-film SFG10.
In order to block the UV component in luminaires with fluorescent tubes, we offer suitable UV filter sleeves (ASR-LY5) for the tubes T5 and T8. These are simply slided over the fluorescent tubes.
The UV filter film can be simply applied to a window pane wetted with a detergent water (e.g. water sprayed with some dishwashing agent). Subsequently, the residentual water then is stroked from the center of the panel outwards, downwards and to the side with a squeegee, so the foil is adheres without bubbles.
It is optimal to attach the foil between two glass panes or between the glass pane and a acrylic glass pane. Alternatively, the film can also be adhered to the window by using UV-resistant adhesive tape SKF-19.
Available sizes:
As standard we supply UV filter foil as a rollware with a width of 122 cm and a length of 10 m.
Roll cut offs are available from 1 m length
Roll lengths up to 700 meters can be supplied on request.
Notes:
The UV coating is applied on both sides of the carrier film. The filtering effect decreases with the passage of time, since the UV filter degrades slowly by the absorption of the UV light. How long the filter effect lasts is determined by the amount of UV light. On external windows to the south side the filter effect can decrease after 1 year, while the filter effect can last up to 10 years on internal windows. It is therefore necessary to check the effect at regular intervals (e.g. every 6 months) with a suitable UV meter.
The UV filter effect is reduced at light wavelengths below approx. 350 nm
Cleaning:
The filter film must not be cleaned with acidic, alkaline or abrasive cleaners, as these can dissolve the emulsion. Use only lukewarm water and a lint-free cleaning cloth (no microfiber cloths!) and wipe the film with only slight pressure.
