AGC (Asahi Glass Company) is one of the world's leading optical glass manufacturers — their glass is used in premium display panels and high-end optics. The HARVES nanotechnology process refines the glass at a molecular level to improve impact resistance and optical clarity beyond standard tempered glass. The result is a protector that maintains the Z Fold 8 Ultra's original display colour accuracy and brightness rather than introducing the slight yellowish tint of lower-grade glass.

Standard tempered glass protectors are 0.33mm. At 0.2mm the H+ Pro is 40% thinner — eliminating the raised-edge feel at the display border and maintaining the original touch sensitivity of the Z Fold 8 Ultra's display. Thinner glass means the touch layer sits closer to the actual display, reducing the air gap that makes some protectors feel slightly less responsive than bare glass.

9H is the highest rating on the pencil hardness scale used for glass testing — resistant to scratching from keys, coins, sand, and everyday objects. The tempered glass construction also provides explosion resistance — when impacted, it shatters into small blunt fragments rather than sharp shards, protecting the underlying display from secondary damage and preventing lacerations from broken glass.

The oleophobic surface coating repels the natural oils from fingers, preventing fingerprint smudges from accumulating on the screen surface — the protector stays visibly cleaner between wipes than uncoated glass. The UV filter coating sits beneath the oleophobic layer and blocks harmful UV wavelengths that can gradually damage OLED display panels and contribute to eye strain during extended screen use.

CNC (Computer Numerical Control) cutting machines the glass edges to precise tolerances specific to the Galaxy Z Fold 8 Ultra's display dimensions, cutout positions, and curve profile. The 2.5D rounded arc edge profile eliminates the sharp 90° corner that standard cut glass leaves — no catching on pockets, no sharp edge contact on fingers during swipe gestures at the screen border.

Silicone adhesive spreads evenly across the display during installation, pushing air out to the edges rather than trapping it in bubbles. Unlike some adhesive types that bond permanently on contact, silicone allows careful repositioning — if the protector is placed slightly off-centre during installation, it can be lifted and reapplied after cleaning without losing adhesion. This is particularly useful for first-time installers.
