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.

¡Ý
To effectively activate
titanium
dioxide, sunlight, mercury
lamps with short wave
length and black lights are
recommended.
¡Ý
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.
¡Ý
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.
