Mixed into a solution
Monovalent copper compound nanoparticles are mixed into alcohol or another liquid.
- Features
-
- In addition to solvents and detergents,
Cufitec® can also be used in paints and other liquids.
- In addition to solvents and detergents,
- Examples of applications
-
- Anti-viral agents
- Disinfectants
- Wet wipes
- Flooring material
- Coatings
When used in an alcohol disinfectant
- Advantages
-
- ●Delivers high anti-viral performance against viruses that are not affected by disinfecting ethanol.
- ●Unlike commercially available alcohol disinfectants, the Cufitec® components developed by our company remain on the surface after the disinfectant dries, and continue to provide anti-viral and anti-bacterial effects.
