The tesa® range contains products that have been developed for short-term, longer-term and permanent bonding. It happens that tapes are not used properly. If, for example, products for short-term outdoor use are left more than three days to weathering and UV stresses, they often cannot be removed without again.
We then recommend the following procedure:
6.1 Tape Carrier
Should be withdrawn slowly and evenly and, if necessary, be warmed beforehand using a hair dryer.
6.2 Adhesive residues
Should be removed step by step:
a.) Rubber adhesives
- The carrier can be pulled off, the adhesive is still soft: removal with mineral spirits.
- The support is brittle and cracks, the adhesive has hardened slightly: heat with a hair dryer and carefully pull; remove adhesive residues with mineral spirits, or: soak, at least, a minute with mineral spirits, then scratch off with a plastic spatula.
- The adhesive has hardened strongly: soak, at least, a minute with universal thinners, then scratch off with a plastic spatula.
- The adhesive has hardened considerably, and the above mentioned procedure was unsuccessful: soak, at least one minute, with Cupran® Hand Cleaner (Evonik Stockhausen, Krefeld), then scratch off with a plastic spatula.
- The adhesive has hardened considerably, and the procedures described above were unsuccessful: Soak with soluwash® Cleaner (Pufas, Hann-Munden) at least one minute, then scratch off with a plastic spatula.
b.) Acrylate adhesives
- The backing is brittle and cracks, the adhesive is easily hardened: heat with a hair dryer and carefully pull.
- The adhesive has hardened: successively try the following solvents or mixtures
- Mixture of 50% ethyl acetate and 50% xylene
- Mixture of 40% alcohol, 40% benzene and 20% acetone
- Cleaner soluwash® S
- The recommended solvent or mixtures may swell the adhesive only, but does not dissolve.
