HERMA’s New Luminophore AdhesiveHERMA has launched an innovative 62L luminophore UV curable adhesive,that allows reliable monitoring of transparent labels with enhanced safety features. The coating of 62L luminophore adhesive takes place with better precision and uniformity as compared to typical commissioned work for luminophore varnishes. In the 13-stage Laetus scale used to measure the intensity of luminescence, the HERMA 62L reaches a value of at least 7 as required for pharmaceutical applications.

Additional Advantages of 62L luminophore UV Curable Adhesive

  • High transparency and extremely high whitening resistance
  • Hand predestined suitable for no-label-look labels
  • Suitable for printing in multicolored UV printing
  • Distinguished by high tack with high cohesion in conjunction with good final adhesion
  • No adhesive leakage
  • High UV stability
  • Good resistance against light, heat, water and ageing
  • Offers low-migration

Secured Labels for Manufacturers and Users

Security features, such as protection against product piracy, are in great demand by industries. To meet the demands, the reliable monitoring of transparent labels with the use of HERMA 62L luminophore adhesive allows enhanced safety both for product manufacturers and product users.

As the labels on pharmaceutical packaging are often transparent for optical reasons, their seamless and reliable presence monitoring using optical sensors is a challenge. To overcome the challenge, the past labels were equipped with luminophores that become visible and detectable as soon as they are exposed to UV light. A special varnish was applied to the labels to achieve the results. However, with the new HERMA 62L adhesive, the luminophores are already integrated during the coating of the adhesive bond.

Better and Complete Distribution of Luminophores

"The coating of the adhesive takes precision and uniformity that is clearly superior to typical commissioned varnish work," said HERMA's head of development, Dr. Ulli Nägele. "This allows us to achieve a better and complete distribution of the luminophores. We also no longer have to monitor whether the varnish was actually applied everywhere and whether there may have been any glitches."
