Introduction:
A cracked or delaminated Samsung S21 Ultra/S20 Ultra screen doesn’t mean you need a full replacement. The right Optically Clear Adhesive (OCA) can restore your display to like-new condition—if you choose the correct thickness and quality.
Why 125µm OCA is Perfect for Samsung Ultra Models
- Optimal Thickness for Curved Displays
- The 125µm (0.125mm) thickness ensures smooth touch sensitivity without interfering with the Ultra’s curved edges.
- Thinner films may lack durability, while thicker ones can reduce touch responsiveness.

- High-grade adhesive prevents air pockets, ensuring a seamless bond with the OLED panel.
- Maintains 98%+ light transmission for vibrant colors and sharpness.
- Durability & Scratch Resistance
- UV-resistant properties prevent yellowing over time.
- Reinforced PET material resists scratches during installation.
Installation Tips for Best Results
✔ Clean the Surface – Remove all dust and old adhesive with isopropyl alcohol.
✔ Use LOCA for Precision – Liquid OCA helps eliminate tiny bubbles.
✔ Apply Even Pressure – A laminator or weighted roller ensures full adhesion.
