Titanium Dioxide acts as a photocatalyst which has strong oxidizing effect when activated by ultraviolet light such as sunlight.
ISK has developed the technology to commercially produce photocatalytic titanium dioxide and to optimize this photoactive characteristics of titanium dioxide.
ST and STS products are capable of decomposing various organic contaminants and offensive odors into carbon dioxide and water by light irradiation. In addition, the photoactivity itself lasts semi-permanently. These products has outstanding stain-preventing effect when especially used in a finishing material for buildings and houses, soundproof walls and guardrails. ST and STS products are also effective in absorbing and decomposing five major malodorous gasses such as ammonia, hydrogen sulphide and acetaldehide, which are considered hazardous in a living space, and volatile organic compounds(VOC). Furthermore, ISK is studying the practical application of the photocatalytic titanium dioxide for decomposing nitrogen oxide (NOx) in air.

 
Characteristics
Usage
Names
To effectively activate
titanium dioxide, sunlight, mercury lamps with short wave length and black lights are recommended.

ISK offers a wide range of
grades that makes ST and STSadaptable to many
different use.The ST is in powder form, while STS is dispersed in water. Grades with extremely large specific surface area, high
photoactivity,excellent
absorptivity and high
dispersibility are available.
ISK has developed many
processed products, such as
honeycomb type filters
suitable for deodorization, coating materials for anti-bacterial and stainproof measures and spherically
granulated catalysts for water treatment.
