Glass screen protectors stick to phone screens using a thin layer of a special adhesive, often referred to as AB glue. Unlike plastic screen protectors which rely on electrostatic adhesion, tempered glass needs this adhesive layer to properly bond to the phone's surface.
AB Glue: The Key to Adhesion
- What it is: AB glue is a type of adhesive specifically designed for bonding glass to surfaces. It's the crucial component that allows the tempered glass to adhere firmly and evenly to the phone screen.
- Why it's needed: Tempered glass itself doesn't naturally stick to phone screens. The AB glue provides the necessary bonding agent.
- Technology: The quality and application of the AB glue are considered a core technology in tempered glass screen protector manufacturing, influencing the protector's clarity, adhesion strength, and lack of bubbles during application.
Application Process
While the glue is pre-applied to the screen protector, the process of applying the protector to the phone screen is critical for proper adhesion. The aim is to achieve even contact and eliminate air bubbles.
Why Not Electrostatic Adhesion?
Traditional plastic screen protectors can sometimes adhere via electrostatic attraction. However, tempered glass is too heavy and rigid for this method to be effective. The AB glue ensures a reliable and lasting bond.
