- Self cleaning effect is needed two properties that decomposed effect and hydrophilic effect.
- Self cleaning effect is mixed decomposed effect and hydrophilic properties. Some mold and bacterial are cleared away by decomposed effect. However put on some blot, air pollutant-formation or bird dropping are keep down to adhesion condition by decomposed, then hydrophilic property is cleared way with rain water.
- Only either property is not able to do self cleaning effect.
- Photocatalysis self cleaning effect is the only ticket.
Self cleaning condition since 2005
