The Glass Chemical Tempering Process

Because thermal tempering requires a minimum thickness of 3mm, and because of difficulties with bending glass, optical quality and distortion etc, more users in different areas (such as air, naval, military, motor, electronic and architectural sectors) require chemically tempered glass. This is because these sectors require glass that varies in thickness and shape. The development of new glass working systems means that chemical tempering can be used in previously curved glass, and also on glass that is less than 2mm thick. The shape of the glass sheet will not be modified during tempering, so perfectly coupled sheets can be obtained during PVB lamination. This article describes the chemical tempering process.
