Durability of Surface Film on Solar Reflective Glass

Abstract

Pinhole phenomena on a surface film on reflective glass were detected in a building that has elapsed 20 years from the completion and has applied the surface film for outdoor. EPMA analysis, SEM-EDX analysis and ESCA analysis were applied the phenomena area and a state of the film was extimated. As a result of the analysis, the phenomena were separated 2 types. One was slight film damage and the other was an adhesion of silica etc on the film surface. Based on the above mentioned, it is expected that TiO₂ film coated on the reflective glass surface has good durability as a building exterior if physical damage has been given on the film in a maintenance procedure.
