Lema will soon complete a new system for chemical tempering of glass size 3200 x 2200 mm. Chemical strengthening is used for extremely thick glass, types of glass where excellent optical quality is needed, printed glass, glass with particular shapes, etc. In all these applications heat tempering has been replaced by chemical tempering.
As a result, this process offers an increased surface compression that strengthens the glass without creating distortion; the glass surface is harder and more resistant to scratching, thus making it possible for thinner glass to be used.
With chemically tempered glass there is no risk of spontaneous breakage and it can be further processed (drilling, cutting, etc.).
