tesa® L-tape 8694

100μm translucent light curable structural bonding tape

Product 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)

Product description

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.

tesa® L-tape is a reactive adhesive tape, which can be activated by wavelengths of 365 nm or 460 nm. tesa® L-tape can be used for bonding of transparent or opaque substrates. tesa® L-tape can be activated before or after lamination onto the first substrate. Transparent substrates such as clear plastics can be bonded before activation by light. At least one substrate must be light-permeable to enable the activation of tesa® L-tape. The bonded parts are then exposed to light to start curing of the adhesive.
