Abstract
A glass substrate is provided with a tin oxide coating. The tin oxide coating is then polished, preferably with alumina. The polishing removes the peaks from the tin oxide coating and produces a less abrasive coating. A coating of polymeric material may be applied after the polishing operation. The polymeric coating improves the lubricity of the surface of the glass substrate. The glass substrate is then heated so that the polymeric material adheres to the substrate. The invention provides greatly improved resistance to abrasion and scratching for a coated glass article. The invention may advantageously be used in automotive, architectual and bar code scanner applications.
