tesa® 6926 LTF-C

Laser Transfer Film - Contrast

Product description

tesa 6926 LTF-C is a dry transfer tape for laser marking. It is suitable for the marking of glass, and is ideal for marking sequential data such as barcodes and reference numbers etc. The tape contains laser sensitive nano composites which are transferred onto the substrate by the use of an appropriate laser marker. The laser beam is transmitted through the glass. Debris can be easily removed.

The high performance LTF-C marking technology is used for identification purposes over the entire lifetime of a product. In addition, it also serves as a data carrier for intelligent inprocess control and monitoring (track & trace).

Main applications

  • Permanent laser marking on glass
  • Individual industrial marking
  • Highly durable and robust against abrasion, chemicals and solvents
  • Very high resistance against temperature and weather conditions
  • Minimal mechanical stress to substrate
  • Cannot be removed without destroying the surface
  • Very high contrast and marking precision
  • Machine Readable
