SMMT high performance Al mirror product V95 is specially designed to attain high specular reflectance and "Indoor Louver-type Light Collecting System" application.
Extreme high total reflectance and 60° specular reflectance are achieved with the classic substrate/Varnishing-coating/Al/SiO2/TiO2 structure, wherein the high performance varnishing-coating deliver a reliable adhesion and extreme smooth surface between Al substrate and PVD coating, meanwhile its substructure SiO2/TiO2 perform as reflectance enhancement and protective layers.
A typical application of this material is the "Indoor Louver-Type Light Collecting System". In order to introduce the outdoor daylight into the indoor no light area or light blind areas, directly use high performance mirror material for a solar collector as a critical part of Indoor Louver-Type Light Collecting System is a most effective, energy-saving and also environmentally-friendly way to solve this problem. In this way, we are confident that our high performance mirror materials can play a key role in People's Daily Lives and make a great contribution to people's quality of life.
