Abstract
A coated article includes a substrate, a first dielectric layer, a first metallic layer, a first primer layer, a second dielectric layer, a second metallic layer, a second primer layer, a third dielectric layer, a third primer layer, a third metallic layer, and a fourth dielectric layer. The total combined thickness of the metallic layers is at least 30 nanometers and no more than 60 nanometers. The article can have a sheet resistance of less than 0.85Ω/□, a visible light reflectance of not more than 10%, and a visible light transmittance of at least 70%.
