Finishfit Microbe Protect 2400

The glossy water-based dispersion varnish Finishfit Microbe Protect 2400 is the result of 18 months of research and development by Epple Druckfarben AG and the start of an innovative product line.

Microbe Protect 2400

 

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 Microbe Protect 2400 is based on a special activated nanosilver-containing formulation. The antimicrobial and antiviral efficacy of the active ingredient has been demonstrated.[1] Moisture causes positively charged silver ions to be released from the elementary silver-nanoparticles that are firmly anchored in the varnish film. These ions 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 a print sample ac-cording 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.

 

Without nanosilver active ingredient

With nanosilver active ingredient

 

  • The antimicrobial and antiviral efficacy of the active ingredient has been demonstrated. [1]
  • The active ingredient is also used in medical masks for protection against viruses. [2]
  • In addition, the active ingredients used are subject to external checks on corona viruses at the renowned University of Groningen.
  • The active ingredient is permanently (24/7) and long lasting active.
  • Silver nanoparticles (Ag) are not released from the dried varnish film nor can they be rubbed off. [3]
