Antimony tin oxide is widely used as a conductive pigment in coatings, plastics, and films due to its excellent electrical conductivity and transparency to visible light. It is commonly applied in anti-static coatings for electronic displays, touch screens, and optical devices where clarity and static dissipation are critical. Its high thermal stability makes it suitable for use in high-temperature environments, such as in automotive and aerospace components. It is also used in energy-efficient windows and solar control films to reflect infrared radiation while maintaining visible light transmission. Additionally, antimony tin oxide finds application in transparent conductive layers for flat panel displays and electrochromic devices. Its resistance to corrosion and chemical stability enhances durability in harsh environments.
