Production equipment for glass coatings
Low-emissivity (Low-E) glass and smart windows are used globally to reduce building energy consumption. To make Low-E glass, a bottom layer of SiO2 and a top layer of SnO2 with fluorine doping (SnO2:F) or antimony doping (SnO2:Sb) are coated on glass by atmospheric pressure CVD (APCVD). By changing the layer thickness and doping concentration, Low-E glass with different optical transmissions and emissivities can be made.
With other coating materials like TiO2 and TiN and different layer structures, smart windows like photo-catalytic and electrochromic glass can be made as well.
APCVD is the low cost, high throughput method to make glass coatings. At CVD Equipment Corporation, we provide offline and online APCVD process equipment for glass coating production.
