The invention relates to a method for producing a glass substrate for vehicle glazing, in particular for a windscreen of a vehicle, which comprises hot forming of a borosilicate glass, wherein in a hot forming section, at least during stretching of the glass () in the flow direction or longitudinal direction of movement of the glass (), an aging velocity Av of the glass () to be hot formed does not exceed 10 mm/s and an aging velocity Av of the glass preferably does not undershoot 3 mm/s, and also relates to glass substrates for vehicle glazing produced by such method as well as to windscreen projection devices and driver assistance systems comprising such glass substrates.

Glass substrate for vehicle glazing, in particular for the windscreen of a vehicle

The method of making borosilicate glass with a surface having reactive SiOH groups on it includes preparing a borosilicate glass melt and dissolving at least 30 mMol per liter of water in the borosilicate glass melt. The borosilicate glass contains from 70 to 87 percent by weight, SiO; from 7 to 15 percent by weight, BO; from 0 to 8 percent by weight, AlO; from 0 to 8 percent by weight, NaO and from 0 to 8 percent by weight of KO. The borosilicate glass with the easily modified reactive surface can be used as a substrate for chemically covalent immobilization of reactive substances. This substrate can be used to make a biochemical chip, such as a DNA or gene chip, or dirt-proof window glass.
