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 |
