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.
