Photocatalyst coating foaming ceramics
Description
Traditional photocatalyst coating with organic binder should be short life time, because photocatalyst decompose organic binder. GiantNano photocatalyst coating with inorganic binder on foaming ceramics is stable under UV light exposure, even UVC and UVB light.
GiantNano Photocatalyst coating foaming ceramics can decompose total volatile organic compound and harmful gases, such as formaldehyde, methanol, NOx, bacteria, virus….
Feature
- High decomposition rate
- long lasting
- easy to clean
- Porosity of foaming can be customized
