Abstract
Disclosed is a novel system for providing transparent electrically conductive tin oxide coatings on substrates, which system includes the steps of doping a tin oxide colloid stabilized with ammonium ions with antimony, coating the resulting mixture onto the substrate to be provided with the electrically conductive coating, and then drying or baking for a time and at a temperature to lower the sheet resistance of the coating to the desired level. In an alternate embodiment, the coating is dried to lower the sheet resistance to provide an anti-static coating.
