Chemical Durability
Durability is measured via weight loss per surface area after immersion in the solvents shown below. Values are highly dependent upon actual testing conditions. Data reported is for Corning Gorilla Glass 5.
Reagent | Time | Temperature (ºC) | Weight Loss (mg/cm2) |

Putting Corning Gorilla Glass 5 to the test.
- Greater damage resistance (upto 1.8X) with deep abrasion.
- Faster chemical strengthening with high Compressive Stress and deeper depth of compression
- Shallower check depth with higher abrasions levels
- Enables thickness reduction
