Antimicrobial screen print varnishes for protection against bacteria and viruses
Permanently sterile front membranes and other screen printing products
These days, hygiene is more important than ever. For this reason, many users are wondering whether it is possible to keep screen print products permanently sterile in the working environment. Our answer is: YES!
Generally speaking, there are two available options. One of them is the use of materials with an antimicrobial coating, about which we have reported before here. The second option is the use of antimicrobial screen print varnishes. These varnishes reliably and permanently eliminate pathogens and have a lasting effect on the hygienic properties of your products.
Mode of action of the varnish
The antimicrobial screen print varnishes contain active silver components which permanently eliminate pathogens. Humidity causes the varnish to release highly reactive silver ions. These ions attack the cell activity of pathogens, prevent them from reproducing and interrupt vital processes, ultimately killing off the pathogens.
