Argentum Plus – special finishing paint that contains virus and bacteria inactivating agent

Tikkurila’s Argentum Plus is a special interior paint which contains silver phosphate glass that protects the painted surface from the growth of bacteria and virus. It is available in matt (Argentum Plus 7) and semi-matt (Argentum Plus 20) versions.

Protecting the paint surface from bacteria

Argentum Plus 7 and 20 are special waterborne topcoats for interior walls and ceilings. They have been designed to protect and beautify surfaces in demanding applications, for example in healthcare facilities where maintaining a high standard of hygiene is extremely important.

Good cleaning practices are essential to achieve a high level of hygiene. To prevent the growth of bacteria on the painted surface, Argentum Plus 7 and 20 contain silver phosphate glass. Both products have been tested according to the ISO 22196 standard (Measurement of antibacterial activity on plastics and other non-porous surfaces) with an exposure time of 24 hours.

Excellent protection against coronavirus

Argentum Plus wall and ceiling paints are proven to speed up the inactivation of coronaviruses that come into contact with the painted surface. Test results show high virus-inactivating activity against bovine coronavirus (S379 Riems) using the quantitative carrier test according to ISO 21702:201. Bovine coronavirus is similar to SARS coronaviruses in structure and genetics, thus these results can be assumed to be the same for similar human coronaviruses. Testing was carried out by Eurofins laboratory (date of test report: 3 February 2022).

Reduced emissions during and after painting

Argentum Plus 7 and 20 are M1-class paints, meaning they contribute to lower emissions during and after painting.

The M1 classification sets maximum limits for the emission of volatile organic compounds (VOCs), formaldehyde and ammonia. The acceptability of the odour is also assessed as part of the classification process. Only materials that emit extremely low levels of compounds into the atmosphere achieve M1 classification.
