Our patented varnish contains silver and copper nanoparticles surface-modified with porous, mixed ceramic material. Nanoceramics increases the stability of silver and copper nanoparticles and their bioactivity, thanks to which they have an extraordinary biocidal effect – they destroy bacteria, fungi and viruses on the coated surface. What is more, unlike other products of this kind used before, they are completely safe for end users and the environment.
