A new high-tech adhesive prevents glass splinters in vehicle crashes.
SCHOTT and DELO® Industrial Adhesives have collaborated to develop an unbreakable glass cover composite for vehicle navigation and entertainment screens, in which a high-tech adhesive bonds the display to the special glass cover. In a series of tests, both companies demonstrated that their new displays satisfy all safety requirements imposed by the automotive industry and protect occupants of vehicles against cutting injuries.
The two companies tested how completely bonded displays behave in a crash compared to conventional displays with an air gap between the glass cover and LCD. For this purpose, they conducted head-on crash tests according to the criteria of the international ECE R21 standard in which a steel ball with a weight of 14.99 lb (6.8 kg) impacts on the displays with a speed of approximately 15 mph (24.1 km/h).
In the tests, the standard displays were completely destroyed by the steel ball, and hundreds of glass splinters were blown off in all directions by the impact. In contrast, only the inner liquid crystal display of the completely bonded displays with the special SCHOTT glass broke. The glass covers remain completely intact, which protects the passengers against cutting injuries. |
