We are developing superhydrophilic coatings.

Hydrophilic coating material using titanium oxide. It has anti-fogging performance, self-cleaning properties due to photocatalytic function, and abrasion resistance!

Our company is developing a hydrophilic coating material using a titania sol liquid in which titanium dioxide (TiO2) is dispersed as nanoparticles. Our hydrophilic coating material excels in hydrophilicity, transparency, and self-cleaning functionality. The superhydrophilicity of titanium dioxide refers to the phenomenon where the surface of titanium dioxide becomes highly compatible with water when exposed to ultraviolet light, causing water droplets to spread thinly and form a film. This allows water droplets to spread across the surface, encapsulating dirt and washing it away, thereby exhibiting a self-cleaning effect. Our titania sol liquid can be applied in various applications such as high refractive index materials, anti-fogging materials, photocatalysts, and anti-reflective materials. By using a single nano-sized titania sol liquid manufactured through our unique sol-gel synthesis technology, it is possible to form transparent and uniform thin films on the order of several tens of nanometers. Since it can form a highly transparent thin film on substrates, it demonstrates anti-fogging performance due to superhydrophilicity and self-cleaning performance due to photocatalytic functionality when applied to automotive mirrors, building glass, outdoor cameras, and more.

basic information

Substrate: Optical glass Optical film thickness: 80nm Refractive index: 2.04 (λ550nm) Contact angle after UV exposure (hydrophilicity): 5.0° or less (Contact angle evaluation after UV-A: 6mW/cm² for 2 hours) *The values above are based on internal evaluations. Results may vary depending on the method of film formation and the type of substrate.
