tesa® 68583
64μm double sided transparent differential filmic tape
Product description
tesa® 68583 is a transparent, double-sided self-adhesive tape consisting of a PET backing and a tackified acrylic adhesive. The coating weight of the outside is higher than the coating weight of the inside.tesa® 68583 features esp.
- Thickness: 64μm
- Asymmetric design
- Higher adhesion level on the outside, lower adhesion level on the inside
- Excellent resistance to demanding environmental conditions
- Excellent handling performance in converting processes
Main applications
- Mounting of two different substrates, where one is easy and the other is difficult to adhere to
- Mounting of components and assembly of electronics devices
Additional Info
- double sided PET liners (36µm easy-release inside / 50µm tight-release outside)
- inside=open side, outside=covered side
