Photocatalyst coating applied to Kimono Quilt Tapestry is Sagan Coat (aqueous solution of peroxotitanic acid), which is developed by KON CORPORATION in Saga Prefecture with patents of the National Institute of Advanced Industrial Science and Technology, Saga Prefecture, Nagoya City, and TOTO
It breaks down harmful organic substances including viruses, bacteria, molds, odor, volatile organic compounds (VOC).
In addition, photocatlyst coating has a self-cleaning effect. Photocatlyst coating applied to exterior walls will break down dirt with light and washed away by rain.
Photocatalyst was discovered by Dr. Akira Fujishima, who completed his Ph. D in the University of Tokyo and is a president of Tokyo University of Science. This is an environmental purification technology which is friendly to people and the earth and Japan should be proud of.
The mechanism of photocatalyst
■When titanium oxide contained in Sagan Coat receives light, it becomes super hydrophilic and produces active oxygen, which has strong resolutive power.
■It resembles photosynthesis of plants very much. In photosynthesis, plants produces oxygen from dioxide and water with the chloroplast as a medium.
Specialties and effects of photocatalyst”Sagan Coat”
Photocatalysis “Sagan Coat” is an aqueous solution of peroxotitanic acid.Since titanium oxide is insoluble in water, other companies use organic solvents. For Sagan Coat, a solvent of purified water is used to make solution of titanium oxide in water (Patent of Saga Prefecture).
Therefore, it is no harmful to human health.
(According to a test result of Japan Food Research Laboratories)
The bird flu virus was broken down and removed by 99.99% in 48 hours.
(According to a test result by Laboratory of Zoo noses, Kitasato University School of Veterinary Medicine)
Photo atalyst “Sagan Coat” remains effective for about 10 years. It doesn’t require any maintenance.
(According to a test result of the Industrial Research Center in Aichi Prefecture)
4 major effects of photocatalyst
1. Self-cleaning
[For exterior walls of buildings, signboards, street lamps, and boutique windows, etc.]
2. Air purification
NOx and SOx can be broken down and removed by applying photocatalyst coating.
Applying photocatalyst coating to exterior walls of residences will bring about the same effects with three ginkgo trees for air purification.
3. Prevent sick building syndromes
Volatile organic compounds (VOC) may cause dizziness, a throat sore nasal inflammation, vomit, and dermatitis in a new or remodeled house. Photocatalysis breaks down and removes VOC.
