The dispersive and polar surface‐energy components, as well as the total surface energy, of tin oxide coatings on soda–lime–silica glass were determined by the Owens–Wendt method. The total surface energy of tin oxide is greater than soda–lime–silica glass and, more importantly, exhibits significantly more‐dispersive and less‐polar character. These results indicate that tin oxide is significantly more covalent than soda–lime–silica glass. It is postulated that the more‐covalent tin oxide coatings increase the bond strength of organic coatings to soda–lime–silica glass. These effects improve the friction‐damage resistance of glass surfaces coated with metal oxides and organics, compared with glass surfaces coated with organics only.
