"TOUGH GLASS" uses high-strength secondary tempered glass, which undergoes conventional thermal strengthening
treatment and then goes through a special chemical hardening process. Through these two hardening treatments,
it achieves all-around strengthening, including the sides and edges. Additionally, the strength of the glass is significantly
improved. The surface is coated with multiple layers, providing not only easy operation and a comfortable touch but
also resistance to smudges, fingerprints, sebum, makeup, and other adherents, which can be easily wiped away.
Two-stage hardening process, Enhanced Strength
For regular LCD glass, thermal hardening involves heating and then rapidly cooling the glass to create internal
and external stresses, generating a state of compression on the surface and within. This process enhances its
resistance to impacts and distortion.
In contrast, the "TOUGH GLASS" series utilizes a secondary hardening process, which includes both thermal
hardening and a special chemical hardening treatment. The chemical agents penetrate the micro-scratches
formed during thermal hardening, further enhancing the glass's hardness.
Dragontrail®
"TOUGH GLASS" is made of Dragontrail® two-stage hardening glass developed by AGC®, Japan. It has 6 time hardness
compared with ordinary glass, and it's also anti-scratch, anti-reflection, and hard to break due to the hardening process
on the edges.
Easy to apply and with a pleasant touching feel
The surface undergoes a multi-layer frosted treatment, achieving a comfortable and responsive touch experience.
While experiencing excellent operational sensitivity, it also resists stains, allowing for easy removal of fingerprints,
sebum, and cosmetic residues with a gentle wipe. Even in the event of breakage, it has undergone special film
treatment to prevent fragments from scattering or causing harm to your fingers.
