Nowadays, the protection against germs and extensive hygienic measures are more important than ever. The antimicrobial screen printing varnishes of Printcolor kill germs reliably and permanently and increase the hygiene of your products lastingly. The varnishes have an antimicrobial mechanism which inhibits enzymatic activity and the reproduction of microbes in the presence of moisture or humidity. The product range includes 2-component, solvent-based as well as UV screen printing varnishes. The varnishes are printed as a top-coat or protection varnish and ensure an antimicrobial effect while preserving the print image.

Mode of action of the varnish

The antimicrobial, colorless screen printing varnishes contain active silver components which permanently kill germs. If the varnish comes into contact with moisture or air humidity, highly reactive silver ions are released. These ions attack the cell activities of germs, prevent them from multiplying and disrupt vital processes – the germs are ultimately killed. As the ions not only target one specific but rather various cell areas at the same time, they have an antimicrobial effect and combat bacteria as well as viruses.

The active agent released on the coated surfaced eradicates over 99.99 per cent of germs, with a germ reduction value of > 3 log levels tested according to JIS Z 2801-2010 NORM.

Product range and application

The antimicrobial varnishes of Printcolor are ideally suited for the print on plastics or metals and applications such as labels, stickers, promotional items, technical components but also hollow bodies such as tubes. They are transparent, clear screen printing varnishes that do not change the appearance of your product. As the silver ions are released in a speed and volume-controlled manner, discoloration of the varnish is prevented. The range consists of four screen printing varnishes:
