sign options for a variety of applications. They’re so versatile, we haven’t even scratched the surface of their possibilities. • Formed from our proprietary fusion process, the glass can be used in the laminate structure “as drawn” without grinding and polishing, thus reducing surface flaws and processing • Applications benefiting from use of thin, lightweight, scratch resistant laminates include: o Architecture: elevator walls and ceilings, building facades, and overhead canopies
o Transportation: automotive, rail, marine, and aviation windows
o Security laminates: bullet resistant glass and blast resistant glazing
• Optical clarity of the glass creates an impression that the material behind the glass is actually on the surface – it’s almost as if the glass “disappears” • Tough and durable, thin Corning Gorilla Glass preserves and helps protect the material beneath it
