Glass chemical tempering
1/Reasons and advantages for glass chemical tempering
The chemical tempering is used when the thermal tempering meets limits.
-Small glass thickness
Even if some suppliers offer now machines able to temper 2 mm thickness glass, the chemical tempering in this case give better results.
-Curved glass
The chemical tempering is done with a temperature around 400°C which don’t change the glass geometrical shape
This is particularly important when the curved glass has to be laminated after tempering.
-The optical quality
Chemical tempering gives better result than thermal tempering when a high optical quality is required.
