We would like to introduce our visible light-responsive photocatalyst, "RunekyatⓇ." A photocatalyst is a functional material that, when exposed to light, not only has deodorizing and odor-preventing effects but also suppresses the growth of bacteria and the activity of viruses. While it has mostly been used outdoors until now, there is increasing attention on its use indoors due to rising hygiene awareness. 【Features】 ■ Unique technology development by Toshiba Materials Co., Ltd. ■ Uses tungsten trioxide (WO3) as the photocatalytic component ■ Good responsiveness to indoor lighting such as fluorescent lamps and LEDs, making it suitable for indoor use ■ Effectiveness lasts as long as the photocatalyst remains (Note: If there are many substances such as tobacco tar or dirt on the photocatalyst surface, you may not experience the effects.) *For more details, please refer to the PDF document or feel free to contact us.
