Construction and Materials
Bulldog uses 2.5D full‑cover high alumina glass with curved edges that follow the contours of the display. The glass is paired with a premium Crown‑brand optical adhesive to ensure strong bonding and stable edge performance over time. This combination is designed to offer higher hardness and better clarity than standard tempered glass.
Strength and Testing
It is rated as 10× strong compared to standard glass based on internal testing.
- In ball drop tests, a 128g ball is dropped from 150–200 cm at least three times without cracking.
- In pressure tests, the glass withstands 40–50 kg of force using a 0.5 mm needle and 0.8 mm margin without rupture.
Coverage and Installation
The 2.5D full‑cover design protects the entire front surface, including the edges. The anti‑static function helps reduce dust attraction during installation, which makes it easier to achieve a clean, bubble‑free result. Compared with more complex liquid‑adhesive systems, Bulldog aims for a simpler and more consistent installation process.
Daily Use and Clarity
High alumina glass offers high optical clarity and maintains screen sharpness and color accuracy. The surface is designed to resist micro‑scratches from everyday contact with pockets, bags, and desks. The strong adhesive bond helps minimize visual artifacts such as micro‑gaps or rainbow effects.
Overall Assessment
Bulldog combines high alumina glass, strong impact and pressure performance, full‑cover 2.5D edges, anti‑static behavior, and premium adhesive. Taken together, these characteristics make it the strongest overall performer in our comparison of premium screen protectors.
