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.
