AGC Dragontrail™ Chemically Strengthened Glass

Download this information as a pdf adobe acrobat logo


Asahi Glass Corporation (AGC) Dragontrail™ is innovative High Ion-Exchange (HIE™) aluminosilicate glass with superior strength, scratch resistance and a beautiful surface finish that is made by applying a proprietary chemical strengthening and tempering process to the highly even and flat float material.


Dragontrail™ supports low profile and reduced weight portable field and industrial devices with a toughness 6x that of soda lime float. It is environmentally friendly and is produced without the use of lead, arsenic and antimony.


Dragontrail™ is an excellent choice of a transparent and damage resistant window or display enhancement glass that helps to enhance the usable lifetime of high contact touch displays, field and industrial image sensors, document scanners and on board vehicular and avionics displays.
