Aqueous type titanium dioxide photocatalyst coating solution
developed by Saga Prefecture Ceramic Research Lab are quite
different from ordinary agent-type TiO2 solutions. The production method and dispertion technique of anatase were invented by Dr. Ichinose of the research lab. Saga Prefecture obtained the Patent in January 1999. Peroxide titanium photocatalyst coating solutions are now acknowledged as the best quality products in the world.
Kon Corporation produces seven kinds of titanium dioxide
coating solutions.
PTA-85/PTA-170
PTA is an amorphous condition aqueous solution. PTA does
not have any photocatalytic functions under room temperature
unless it is heated to more than 250 degrees centigrade.
A very fine titanium dioxide film can be made on a surface of a
substrate at room temperature. It can be used as a protection
layer for an organic substrate. After it is dried completely the
coated film with TiO2 nver dissolve in water. PTA-85 is suitable
for spray coating and PTA-170 is used for dip coating. |
TO-85/TO-240
TOsol differes from PTA. It is already crystallized and shows
the strong photocatalytic activity when it is coated and dried.
In case of flat and smooth surface the TiO2 coated to the
substrate comes off as a powder when rubbed with a finger
because TOsol cannot form a hardness film at room temperature.
However the hardness of the film coated with TOsol can be
improved when it is heated to a certain temperature.
TPX-85/TPX-220
TPX is a mixed solution of PTA and TOsol. A film coated by TPX
achieves photocatalytic effect and hardness strength of the film
after drying at room temperature. The film hardness becomes 2H
to 5H. TPX is a neutral solution that can be allied to various
materials including metal and resin. Photocatalytic effect and
hardness of the film can be increased when it is heated within
the permissible high temperature of the substrate. A coated film
does not decrease the hardness due to the time change.
TPX-HL / Visible light type
TPX-HL solution can respond to visible light wave of 490 nm.
TPX-VB / Sterillizing type
TPX-VB is produced by a new and existing combined technology
to increase the sterillizing function in a dark room.
TPX-AD / Powerful absorbent type
TPX-AD has strong absorbent properties to decompose organic
compounds.
TPX-HP / Super hydrophilicity
It is a suitable coating solution for window glass.
