A film coated with particles of Antimony-doped Tin Oxide can effectively produce an anti-static effect. However, this process can bring reduction to the film’s transparency – an unattractive side-effect. The transparency problem is conquered by decreasing the particle size to nanoscale and controlling its dispersion. Sukgyung AT’s ATO series shows very high transparency along with its anti-static effects. The ATO-coated film also exhibits absorption of wavelengths in the infrared range, making it ideal for IR-controlled environments by providing a virtually energy-free protection.
