A New Generation of Temperable Coatings

Glass markets dominated by architectural rather than residential glazings typically require greater use of tempered glass. Tempering glass before coating results in a wide variety of cut sizes that must be coated, which reduces the loading efficiency and economics of the coating system and other down-stream processing. The logistics of cutting, coating and fabricating tempered and coated glass may then favor the use of posttemperable coatings.

The ability to deposit solar reflective and low-emissivity coatings that can survive tempering requires understanding and controlling glass handling, washing, grinding and tempering as well as the coating materials and processes. New designs of sputtered low-emissivity and solar reflective coatings will be presented which can be post tempered. Key areas of glass fabrication that must be controlled for successful coating and tempering will be reviewed. Optimization of material selection and process conditions provides designs that are compatible with existing coater configurations for standard products. The use of flexible compartment coating systems with high pumping speeds and control of gas isolation optimizes the production of these new coatings.
