When UV lamps are active, they generate great ultra violet radiation, in the necessary spectrum, initiating the chemical reaction necessary for the curing of an ink. This radiation of light also generates a significant emission of heat that is projected onto the substrate or the printing table and can affect self-adhesive materials. Although today’s lamps, especially LED curing lamps, are designed to dissipate much of that energy, temperature can negatively affect adhesives and the thin film that supports them.
Flat digital printing tables require the use of tapes to fix positioning stops or to concentrate the gap in the area where the substrate is placed. These adhesive tapes are going to receive a large amount of UV radiation during the printing process and at the end of it we must remove them.
For this reason, TESA has developed special adhesive tapes that are highly resistant to UV rays and to the temperature received, so that they can withstand exposure and end the run, we can easily remove them without breaking or leaving adhesive residues on the table.
There are two options:
TESA 4440 adhesive tape:
- More flexible paper
- Greater durability applied
- Sharp and precise profiles
- Can be cut by hand
- Good anchoring of paint / sealant
- Acrylic adhesive
TESA 50600 adhesive tape:
- Translucent green polyester support
- Blade cut
- Resistant to high temperatures
In both cases they offer resistance to UV drying and are easy to remove without leaving adhesive residue on the table.
We have many other adhesive tapes for industrial solutions, if you need a proposal our commercial technical department can help you find a solution.
