Screen protector 3MK HardGlass Max for Samsung Galaxy S8/S9 Plus — tempered glass, model 3mk HardGlass Max(96)

3MK HardGlass Max for Samsung Galaxy S8/S9 Plus is a tempered glass screen protector engineered to provide reinforced protection across the entire front surface, including curved edges. With a 0.3 mm thickness and high optical clarity, the protector preserves original color saturation and display sharpness while maintaining full touch responsiveness for gaming and everyday use. The product kit includes the tempered front glass, Anti-Bubble Card™, wet and dry cleaning cloths and is designed for precise, bubble-free installation.

Advantages

HardGlass Max features a 9H surface hardness that resists scratches from hard steel objects and daily wear. The glass undergoes a prolonged tempering process at 420 °C to achieve high durability and impact resistance, while reinforced 3D edges provide improved coverage on curved screens. An oleophobic coating reduces fingerprints and streaks and ensures smooth finger glide. The Inviscid-Sil™ adhesive minimizes air bubbles and improves edge adhesion for a neat fit.

• Users who need scratch and minor impact resistance while preserving touchscreen sensitivity

How to use

Before installation, clean the device screen thoroughly with the wet and dry cloths provided to remove dust, grease and particles. Peel the protective film from the adhesive side of the tempered glass, align the protector precisely with the phone screen and place it gently from one edge to the other. Apply light pressure in the center to allow the Inviscid-Sil™ adhesive to spread and push remaining bubbles outward using the Anti-Bubble Card™. If necessary, lift and re-align immediately; once the adhesive sets, avoid removing the protector repeatedly.

Usage recommendations

For best results, install the protector in a dust-free environment and avoid pressing the edges aggressively during installation. Clean the surface periodically with a soft, lint-free cloth and a mild screen-safe cleaner; do not use abrasive chemicals. Note that compatibility may be affected by some third-party accessories such as certain cases or screen frames.
