PTA-85/PTA-170 PTA
is an amorphous condition aqueous solution. PTA does not have any
photocatalytic function under room temperature unless it is heated
to more than 250C A very fine titanium dioxide film can be made
on a surface at room temperature. It can be used as a protection
layer for an organic substrate. PTA-85 is suitable for spray coating
and PTA-170 is used for dip coating. When it is heated to more than
250C the amorphous condition becomes a structure of anatase crystal.
Heat treatment of more than 800C changes the anatase crystal to
rutile causing its photocatalytic effect decrease. PTA-85 is recommended
to use for producing photocatalytic tile.
TO-85/TO-240
TOsol differs from PTA. It is already crystallized and shows the
photocatalytic activity when it is coated and dried. In case of
flat and smooth surface the TO coated to the substrate comes off
as a powder when rubbed with a finger because TOsol cannot form
a hardness film. However, the hardness of the film coated with TiO2
can be improved when it is heated to a certain temperature. TO-85
and TO-240 are suitable for dip coating. Spray coating also be used.
TO is already crystallized to anatase so that it shows the photocatalytic
function when it is coated and dried at room temperature. However,
it is more efficient to conduct high temperature heat treatment
that corresponds to the substrate in order to improve its various
activities and adhesion.
TPX-85/TPX-220
TPX is a mixed solution of PTA and TO. A film coated TPX achieves
photocatalytic effect and hardness strength of the film can be made
after drying at room temperature. TPX is a neutral solution that
can be applied to various materials including metal and resin. A
coated film with TPX never dissolves in water. Photocatalytic effect
and hardness of the film can be increased when it is heated. Spraying
coating is the most suitable way for TPX. But substrates can be
dipped into the TPX liquid or applied by brush. The film's hardness
decreases when it is not sufficiently dried. Photocatalytic activity
and the hardness of the coated 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.
