Types of AB Glue Used in Tempered Glass Screen Protectors & Their Quality Differences
AB glue is a specialized adhesive used in tempered glass screen protectors to ensure strong adhesion to the device screen while maintaining clarity and touch sensitivity. The quality of AB glue affects factors like bubble resistance, durability, transparency, and reusability.
At G-Tel Glass Factory, we specialize in high-quality tempered glass screen protectors using premium OCA and UV-cured AB glue to ensure maximum clarity, durability, and strong adhesion. Below is a detailed breakdown of different types of AB glue, their characteristics, and how they impact screen protector performance.
1. What is AB Glue?
AB glue is a two-component adhesive system consisting of:
- A Component (Adhesive Base): Provides adhesion and bonding strength.
- B Component (Curing Agent): Helps in curing and solidifying the adhesive after application.
The combination of these two ensures that the tempered glass adheres securely to the screen without bubbles while allowing easy removal when needed.
2. Types of AB Glue for Tempered Glass
(1) OCA (Optically Clear Adhesive) AB Glue - Premium Quality (Used by G-Tel Glass Factory)
✔ High transparency (99%+ light transmission)
✔ No yellowing over time
✔ Excellent bubble-free application
✔ Best touch sensitivity & clarity
✔ Used in high-end tempered glass protectors
🔹 Best for: Ultra-clear, high-end screen protectors (used in premium brands and by G-Tel Glass Factory for superior optical clarity).
(2) UV-Cured AB Glue - High Quality (Used by G-Tel Glass Factory)
✔ Cures under UV light for strong adhesion
✔ Good bubble-free application
✔ Better reusability than standard glue
✔ Good touch sensitivity
✔ Slight risk of residue if removed incorrectly
🔹 Best for: Curved edge protectors (full adhesive 3D glass), commonly used in high-end protectors for Samsung Edge displays.
🔹 G-Tel Glass Factory uses UV-cured AB glue for curved and full-coverage tempered glass protectors, ensuring long-lasting adhesion and crystal-clear visibility.
(3) Standard Silicon-Based AB Glue - Mid-Range Quality
✔ Moderate transparency (90-95%)
✔ Self-adhesive and reusable
✔ May develop air bubbles over time
✔ Can weaken over repeated removals
✔ More affordable, commonly used in mid-range screen protectors
🔹 Best for: Budget-friendly tempered glass protectors with decent adhesion.
(4) Acrylic-Based AB Glue - Low-Quality
✔ Lower transparency (~85-90%)
✔ Prone to yellowing over time
✔ Easier to peel off but weaker adhesion
✔ Higher chance of bubbles and edge peeling
✔ Low-cost option for basic screen protectors
🔹 Best for: Low-end or temporary screen protectors (often seen in very cheap products).

5. How to Identify High-Quality AB Glue in Tempered Glass?
✔ Look for OCA or UV-Cured adhesive for better clarity and strong adhesion.
✔ Check for bubble resistance—premium AB glue should apply smoothly without air bubbles.
✔ Ensure no yellowing over time—low-quality glue turns yellow after prolonged use.
✔ Touch responsiveness should be seamless—cheap glue may reduce screen sensitivity.
