New Functional Material Technology
- Eco-Friendly Ultra-Hydrophilic Inorganic Coating Materials with Anti-Corrosion and Anti-Microorganism Functions
- Super Hydrophilic Anti-Fouling
- Since it has a superhydrophilic property with a contact angle of around 10°, it is difficult to adhere to various contaminants such as water stains, and the adhered contaminants can be simply washed with water.
- Excellent Corrosion Resistance Anti-Corrosion
- Corrosion resistance in strong acid and strong alkali environments including brine (sea water) is very good.
- Powerful Sanitizing Anti-Biofouling
- The use of inorganic antibacterial substances registered as disinfectants in the U.S. FDA can remove not only various bacteria but also infectious viruses.
