Corning® Gorilla® Glass

Corning’’s New Gorilla® Glass 3 with Native Damage Resistance™™ – is an alkali-aluminosilicate thin sheet glass that is better able to survive the real-world events that most commonly cause glass failure. With its new core composition, this glass enables improved damage resistance and toughness by helping to prevent the deep chips and scratches that cause glass to break.

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’s Gorilla Glass 3 with NDR™™.

Reagent Time Temperature (C°) Weight Loss (mg/cm2)
HCl – 5% 24 hrs 95 0.6
NH4F:HF – 10% 20 min 20 2.1
HF – 10% 20 min 20 12.3
NaOH – 5% 6 hrs 95 1.9

Putting Gorilla® Glass 3 with NDR™ to the Test

Greater damage resistance

Corning® Gorilla® Glass 2
It takes more load to initiate radial cracks in the glass.

 

Enables the use of thinner cover glass

Corning® Gorilla® Glass 3
Devices benefit from greater retained strength.

 

Enables greater strength

Corning® Gorilla® Glass 4
Corning Gorilla Glass 3 with NDR™ exhibits tighter strength distribution.

 

Greater retained strength

Corning® Gorilla® Glass 5

 

Scratches are less visible

Corning® Gorilla® Glass 6
