Innovative Reactive Films and Tapes Three Advanced Technologies

Reactive films and tapes are dimensional precise and pre-applicable. This guarantees quick and clean processing. Besides both thermally activated tape technologies, polyurethane and epoxy, Lohmann developed a UV- activatable tape technology called UV-LUX® which has semi-structural properties through a cross-linking mechanism.

Combined High-tech Technology for Completely New Solutions

Industry’s demands on hightech bonding systems are increasing. Today, numerous safety components or entire assemblies are optimally connected using only adhesives. 

With their reactive product range Lohmann has provided the answer to these industrial challenges.

Within the scope of structural bonding, we have developed innovative products that are much stronger than conventional pressure-sensitive adhesive connections.

Also, they combine semi-structural and structural bonding performance with the ease of handling known from adhesive tapes.

 

UV-LUX®
UV-Activatable Tape

UV-LUX Technology, the world's first UV-light activatable adhesive tape solution with color change, is an allrounder we have used in automotive production for more than 5 years. Cold chains and thermal activation become obsolete. Translucent or thermal resistant materials are no longer needed to activate crosslinking. Apart from an initial tack and defined dimensions a color change mechanism ensures precise, easy and safe manufacturing processes. For several years, the technology has been embeded in automotive applications, and the potential number of further applications is indefinite.

 

Technology: 
  • Modified UV-activatable Epoxy
  • Tapes with initial tack
  • Formulation and thickness vary depending on application

Process:
  • UV-activation with 365nm and 385nm wavelength within seconds
  • Color change at activation (optional)
  • Up to 10 min. open time
  • Immediate handling strength for further processing
  • Full strength 24 hours after activation

Your benefits:
  • Can be processed like a conventional PSA tape
  • Improved processing: color change indicating correct activation and open time to safely join non-transparent parts

  • Structural properties

  • UV-activation in less than 3 seconds as well as curing with no additional energy in the dark is possible

  • Aging resistant

Lohmann's SBF range combines structural bonding performance with the ease of use offered by adhesive tapes.

It comprises two chemistries: epoxy and polyurethane.
