The "Peel" Experience

For Screen Protectors and Adhesives, the user experience is defined by Peel Strength.

- The Issue: If adhesion is too high, the film leaves a sticky residue on the screen. If too low, it bubbles and falls off.

90° Peel Testing Mastery

The KHT WDL Series excels in low-force adhesion testing.

- Solution: Equipped with a Floating Roller Fixture, it performs the standard 90° Peel Test (ASTM D3330). The 0.5 Class accuracy ensures that even subtle variations in adhesive coating thickness are detected.

- Data Analysis: Our software automatically calculates the "Average Peel Force," eliminating the noise from initial bonding irregularities.
