Sili-Kill - Antimicrobial SiO2 Nanoparticles

Summary

SiO2 nanoparticles are suitable for antimicrobial coating, especially in the sanitary and wet areas. In principle, however, all surfaces can be coated with it. In addition, the coated surfaces show a strong water and dirt repellent effect.

Technology Benefits

Round coated nanoparticles
Surfaces have a purely contact active microbial effect
Dirt-repellent
Effective against mold

Technology Application

The new SiO2 nanoparticles are suitable for the antimicrobial coating especially in sanitary and wet areas, for example, of silicone joints. However, all surfaces in principle can be coated with them.

Detailed Technology Description

A special process to coat SiO2 nanoparticles around with biocidal quaternary ammonium silanes has been achieved, so that the biocidal moiety points always outwards. Subsequently, the nanoparticles can be deposited on one surface from a dispersion of a simple solvent (for example alcohol). The forming surface coating acts purely contact active antimicrobial. That means, when touching, no toxic substances go over the contacting body.
