Aluminosilicate glass sheet for intelligent Tft Lcd display panel screen glass cover processing
Ultra Clear Medium Aluminosilicate Electronic Float Glass(CHIYAN-M2) is an eco-friendly ultra clear alumino-silicate glass with certain strength.
Glass Type: Float glass
Screen printing glass is a process of using high-temperature ink to form patterns on the surface of glass through screen printing technology. After tempering or high-temperature baking, the ink is tightly combined with the glass surface, Unless the glass is broken, the pattern and glass will not separate. The surface of the glass is smooth and flat, making it easy for screen printing processing. It can screen various colors that customers need; The glass screen printing ink used has the effect of being resistant to high temperatures and not falling off.

Product Composition
Ultra Clear Medium Aluminosilicate Glass achieves better stress and strain depth than ordinary soda-lime glass by increasing the Al₂O₃ content in the glass and increasing the ion exchange capacity.
