Finishfit® WBC Gloss


Field of application

The field of application of the water-based gloss varnish ranges from pharmaceutical and food packaging, magazines, playing cards and other printed products that require active surface protection. Finishfit® WBC Gloss Microbe Protect 2400 is based on a special activated nanosilver-containing formulation. The antimicrobial and antiviral efficacy of the active ingredient has been demon-strated.1) Elementary silver-nanoparticles (Ag0) that are firmly anchored in the varnish film re-lease positively charged silver ions (Ag+), which significantly reduce the number of bacteria and viruses on the surface of the varnish.

The functionality of the active ingredient in the varnish was proven on print samples according to ISO 22196 against the bacterial species

  • Escherichia-coli (E. coli)
  • Staphyloccocus aureus (S. aureus)

and showed a reduction of up to 99.99%. The effectiveness depends on the concentration of the active ingredient.
