1 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 InformationBenefits glass designed with improved native damage resistance, - Enhances retained strength after use - High resistance to scratch and sharp contact damage - Superior surface qualityApplications Ideal protective cover for electronic displays in: - Smartphones - Laptop and tablet computer screens - Mobile devices Touchscreen devices Optical components High strength glass articlesDimensionsAvailable thicknesses mm - mmViscositySoftening Point (10 poises) 900 CAnnealing Point (10 poises) 628 CStrain Point (10 poises)
