ETUN-85 / ETUN-170 ETUN is an amorphous condition aqueous solution. ETUN has any photocatalytic function under room temperature. 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. ETUN-85 is suitable for spray coating and ETUN-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. ETUN-85 is recommended to use for producing photocatalytic tile. ETN-85 / ETN-240 ETNsol differs from ETUN. It is already crystallized and shows the photocatalytic activity when it is coated and dried. In case of flat and smooth surface the ETN coated to the substrate comes off as a powder when rubbed with a finger because ETN sol 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. ETN-85 and ETN-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. ETSN-85/ETSN-220 TPX is a mixed solution of ETUN and ETN. A film coated ETSN achieves photocatalytic effect and hardness strength of the film can be made after drying at room temperature. ETSN is a neutral solution that can be applied to various materials including metal and resin. A coated film with ETSN 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 ETSN. But substrates can be dipped into the ETSN 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.

Traditional manufacturing method of photocatalyst Titanium Dioxide used strong acid or solvent to dissolve Titanium Dioxide in liquid form. But these photocatalyst products tend to be highly acidic and contain high level of Volatile Organic Compound. Another disadvantage of this traditional photocatalyst titanium dioxide solution is that Titanium Dioxide in the solution sometimes forms white deposit and renders the solution to be unusable. ELECS’s Photocatalyst Products are truly the breakthrough in dispersing nano-sized Titanium Dioxide in aqueous form. Using patented manufacturing process and chemical formula; ELECS’s Photocatalyst products are neutral and contain no VOC. Titanium Dioxide particles in our products would not form any deposit which prolongs left expectancy of the product.
