New trends in the automotive and construction industries are leading manufacturers to develop new materials with added value. In this article, we deal with the introduction of such a material, namely a silver-based emission coating, which is used in both architecture and the automotive industry. Silver-based coating thus makes it possible to increase the driver’s comfort, or to increase the comfort of working in the office on hot steamy days. This coating changes the transmittance of IR radiation from or to the building, or from or to the car. The coating is based primarily on the presence of layers of silver, which are able to provide the primary functions of modulation of incoming and outgoing radiation. Silver-based coatings can also be used to heat, for example, car windshields. The production of a silver-based coating is very demanding and sensitive to the formation of coating defects. In this article, we discuss common coating defects and discuss their possible origins.
