Surface-Energy Determinations Of Tin Oxide-Coated Soda-Lime-Silica Glass

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. It is postulated that the more covalent tin oxide coatings increase the bond strength of organic coatings, thus improving the fraction-damage characteristics of cold-end + hot-end coated containers compared with surfaces treated with organics only.
