Photocatalyst
When exposed to ultraviolet light, the effective photocatalytic titanium oxide is used as a raw material, and reacts with phosphoric acid, through oxidation-reduction, and oxidizes with water molecules in the air that do not require light, thereby leading to a catalytic reaction.

 Non-photoactive catalyst
The non-photocatalytic coating is a breakthrough coating that can produce high effects even in the dark, such as antibacterial, deodorant, antifouling and mildew resistance.

Comparison of photocatalyst and Non-photoactive catalyst

Non-photoactive catalyst  photocatalyst
Irradiation of ultraviolet light and fluorescent light No Yes
Organic binder No Yes
Adhesion Strong Weak
Change with time High durability Deterioration of high-durability adhesives and materials
