This is a case study of photocatalytic treatment on the exterior walls and glass of a bank branch (anti-soiling measures).
The decomposition of organic dirt using photocatalysts and self-cleaning will break down the substances causing dirt on the exterior walls and glass of banks, allowing them to be washed away by rain and creating a clean environment.
【Exterior Photocatalyst】 We will apply a photocatalyst coating for exteriors. When it rains, the coated surface becomes hydrophilic, enabling the decomposition of organic dirt and providing a self-cleaning effect. The rain helps wash away dirt, effectively contributing to anti-soiling measures for the building's exterior. It is also effective in reducing cleaning maintenance costs. 【Glass Photocatalyst】 We will apply a photocatalyst coating for glass. When it rains, the coated surface becomes hydrophilic, providing a self-cleaning effect and allowing rain to wash away dirt, effectively contributing to anti-soiling measures for glass. It is also effective in reducing cleaning maintenance costs.

basic information
【External Photocatalyst】 ● The construction uses a dedicated low-pressure hot air painting machine for photocatalysts to minimize painting loss and ensure efficient application. ● A photocatalytic aqueous solution (titanium dioxide solution) specifically for external use is applied as a coating. ● For organic surfaces such as painted areas, a primer is pre-coated to prevent degradation of the surface due to the photocatalyst. ● Different primers are used for coating surfaces that are water-absorbing and water-repellent. ● When rain hits the photocatalytic surface, it becomes hydrophilic (self-cleaning effect) and decomposes organic dirt, creating a clean environment. ● It effectively reduces cleaning and maintenance costs. 【Glass Photocatalyst】 ● The construction uses a dedicated low-pressure hot air painting machine for photocatalysts to minimize painting loss and ensure efficient application. ● A photocatalytic aqueous solution (titanium dioxide solution) specifically for external use is applied as a coating. ● The condition of the glass (new, existing, deteriorated, etc.) is checked, and surface preparation is done to achieve a hydrophilic state through polishing or other means. ● When rain hits the photocatalytic surface, it becomes hydrophilic (self-cleaning effect), allowing dirt to wash away with the rain, creating a clean environment. ● By reducing and suppressing dirt adhesion, it also helps lower cleaning and maintenance costs.
