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 heated glass and energy-efficient windows. It is also used in transparent electrodes, solar cells, and electromagnetic interference (EMI) shielding materials. In addition, antimony tin oxide finds application in catalyst supports and wear-resistant coatings because of its durability and chemical inertness under harsh conditions.
