Wall paint eliminates corona viruses with silver technology

A few years ago, together with the Fraunhofer Institute for Chemical Technology, Bioni CS developed wall and facade paints that could be protected against mould and bacterial infestation with the help of nano-silver technology. In the course of further research, an interior paint has now been developed that, in addition to multi-resistant bacteria, also reduces corona viruses on the paint surface by more than 99.9%.


It is not only since the Corona pandemic that building-related, technical measures to prevent the spread of pathogens in public buildings have increasingly come into focus. Risk reduction measures are particularly important in places where sensitive or immunocompromised people spend long periods of time, such as schools, nursing homes for the elderly or hospitals. In addition to regular cleaning and (contact) surface disinfection as well as modern air filtration systems, antibacterial light switches and door handles, for example, are therefore increasingly being used there. The interior paint, which is sold under the product name "Bioni Hygenic Pro", can also be used here.



Silver system technology and biopolymer provide protective mechanism

The new interior paint achieves its anti-viral surface properties and its effective protection against gram-positive and gram-negative bacteria with the help of a special combination of active ingredients. The raw materials, based on a silver-doped poly-silicate, silicate light fillers and a special biopolymer, enable a uniform bioavailability of silver ions on the surface.


Corona viruses on the surface of the paint were reduced by 99.92% (3 log levels) within 24 hours, methicillin-resistant Staphylococcus aureus (MRSA) even by more than 99.99% (4 log levels).
