CMC 77701 is an ETFE adhesive tape which is equipped with a polysiloxane adhesive on one side. The CMC 777xx product family comprises extremely aging-resistant adhesive tapes for use as a fixing and repair tape for roof and facade constructions. The adhesive is adapted to the high requirements of the surfaces to be repaired. It is long-term resistant to immersion by water. The base film used (ETFE) is good dirt repellent and is used regularly for architectural applications. Due to the UV stability as well as the weather resistance, this adhesive tape is also used in the solar sector.
The ETFE adhesive tape CMC 77701 is supplied with a liner, which allows very easy cutting and processing on the construction site.
