Verfahren zur Hydrophilierung von Glassubstraten und deren Verwendung

The process for making glass substrates hydrophilic comprises reacting (i) silane(s) (I) with hydrophilic organic group(s) R' and free hydroxyl (OH) and/or OR group(s) with (ii) the glass substrate to form Si-O-Si linkages between the silane and Si-OH groups of the glass substrate; and selecting the R' group(s) so that the angle of contact between the treated glass substrate and water is < 22 deg. . USE - The treated glass substrates are used e.g. in vehicles (claimed), e.g. as windscreens. ADVANTAGE - The present treatment improves the wiping quality, has high long-term stability and causes little scattering of light. It also prevents drops of dew or rain forming, which otherwise would also reduce visibility.
