VITOLEN
111 UVR
First choice for use under high UV radiation
VITOLEN 111 UVR (UV-resistant) is the material of choice when the product is exposed to high levels of UV radiation. Among other things, it was developed as a UV-stable heat protection tape for foil greenhouses / tunnels, where it protects the foil against thermal and mechanical damage. For this purpose, metal frame work as well as its sharp-edged areas are covered by the one-sided self-adhesive VITOLEN 111 UVR before applying the greenhouse / tunnel foil.
Due to the acrylic adhesive treated with a UV stabilizer, the UV radiation does not damage the foam of VITOLEN 111 UVR, so that it does not disintegrate despite intense sunlight.
Extensive tests have shown that the laminated film of the tape is also protected by this adhesive.
The high-end acrylic adhesive is in itself resistant to UV, aging, weathering and temperature, in contrast to the commonly used inexpensive caoutchouc-based adhesives.

Product benefits
- High UV resistance
- Good adhesion on different surfaces
- The closed-cell foam absorbs nearly no moisture
- Resistant against water and a large number of usual chemicals
- Very good thermal insulation properties
- Easy and quick application without rubish – no liner to be disposed-off
Excerpt of the weathering test
Parameters: 8 hours of UVA radiation and 4 hours of condensation alternately.
The literature (1) provides the rough correlation for UVA-340 lamps: 1.000 hours (42 days) corresponds to about one year of outdoor use.

Summary
Unprotected PE foams are severely damaged within approx. 3 years of outdoor weathering and then show recognizable cracks and furrows.
Products that are laminated with low-cost hot-melt rubber adhesives, as used up to now, show this behavior after a much shorter time.
By adding a suitable UV stabilizer in a high-end acrylate pressure-sensitive adhesive, no change in the surface can be observed even after more than 3,000 hours of accelerated aging.
