tesa® L-tape 8694 is a translucent light curable structural bonding tape. The curing process starts upon exposure to UV or blue light (standard 365 nm or 460 nm lamps). tesa® L-tape has initial tack for easy application of the adhesive before curing. Sufficient open time after activation allows bonding of both transparent and opaque components. tesa® L-tape comes with an immediate high bonding strength, which avoids additional fixation steps after initial bonding.
FEATURES
- High bonding performance, even on small bonding areas and thin design gaps
- Tacky at room temperature
- Bonding of translucent or opaque substrates
- Immediate bonding strength after activation
- Easy die-cutting process (PET Reinforced)
APPLICATIONS
- Bonding of temperature sensitive substrates
- Component mounting in electronic devices
