THIN FLEXIBLE GLASS COVER WITH A FRAGMENT RETENTION HARD COATING

Abstract:

Glass articles having a thin glass layer and atop optically transparent polymeric hard-coat layer disposed on atop surface of the thin glass layer. The top optically transparent polymeric hard-coat layer may have a thickness in a range of 0.1 microns to 200 microns and a pencil hardness of 6H or more, when the pencil hardness is measured with the optically transparent polymeric hard-coat layer disposed on the top surface of the glass layer. The glass articles avoid ejection of glass shard particles from the glass article upon bending to a failure during a static two-point bend test.
