For the bonding of add-on parts to glass in the automotive sector, Lohmann has developed a UV-light activatable double sided tape, that makes the process faster, safer and more sustainable: UV-LUX®. It combines the fast process of a pressure sensitive tape with the strength of a reactive adhesive.
|UV-activation < 3 seconds||No creeping||No pretreatment on glass|
By eliminating the need for primers, activators and the cool chain, Lohmann makes processes more efficient and sustainable. Both the short activation time (10 times faster compared to state-of-the-art UV reactive liquid adhesives) as well as the immediate handling strength enable uniquely short process times for a reactive adhesive bond. The final bond meets the high requirements of the automotive industry regarding temperature, moisture and aging resistance.

High humidity and aging resistance
The epoxy chemistry gives our products a high moisture and aging resistance to withstand typical industry tests such as PV1200 and Cataplasm. The temperature resistance ranges from -40 °C up to 105 °C.
Our UV-LUX products combine the ease of use of a pressure sensitive adhesive (PSA) tape with the strength and durability of a semi-structural bond after curing. The semi-structural strength allows our products to require less bonding area to attach a component.
Activation detection through color change
A color chage from blue to pink initiated by UV-light ensures a sufficient activation and enables a visual check within the process.
Delivery of equipped parts
We deliver ready to use add-on parts with a fingerlift option for an easy liner release. This can significantly reduce complexity within your production process.
Cationic curing mechanism
After activation our tape has an open time of 5 minutes to apply it on the glass. That allows us to bond non translucent attachement parts (i.e. GFRP) to the ceramic frit of the glass.
To hold the glass in position during the PU-adhesive curing process, Lohmann’s UV-LUX® tape provides locator pin bonding with semi-structural strength. The final bonding strength and static shear resistance allows to bond even heavy glasses without creeping or sliding. This allows to enable perfect gap dimensions between the glazing and the car body.
