Screen protector needs to do more than simply cover the display. During daily use, phones can be dropped, pressed inside a bag, bumped against hard objects, or repeatedly touched throughout the day.
The KK9 super tough screen protector is designed to provide stronger protection while maintaining the clear, smooth screen experience users expect. Through a dual-strengthening process, the glass achieves high internal strength, allowing it to withstand strong bending, impact and edge pressure without easily breaking.
Combined with high light transmittance, plasma-applied oleophobic coating and precision model development based on real devices, it delivers a balance of durability, clarity, smooth touch and accurate fit.
The super tough screen protector undergoes a dual-strengthening process to improve its internal strength and structural stability.
This gives the protector excellent flexibility for strengthened glass. It can withstand extreme bending, including O-shaped bending tests, without easily cracking or breaking.
Accidental drops and direct impacts are among the most common causes of screen damage.
The KK9 super tough tempered glass has passed a 64 g steel ball drop test from a height of 2 meters, demonstrating strong resistance against concentrated impact.
This reinforced structure helps absorb and distribute impact energy before it reaches the phone screen.
The edge is often the weakest area of a tempered glass screen protector. Once the edge is damaged, cracks can quickly spread across the entire glass.
To address this problem, the KK9 screen protector uses an enhanced edge-strengthening and anti-chipping process.
The reinforced edge can withstand approximately 25–30 kg of pressure, helping reduce edge cracking and chipping during installation, transportation and everyday use.
A screen protector is touched hundreds of times every day. Without a good surface coating, fingerprints, grease and smudges quickly become visible and affect both clarity and touch feel.
The glass surface uses a plasma oleophobic coating process, creating a smooth surface that helps reduce fingerprints, oil and everyday stains.
The result is a cleaner-looking screen with a smooth sliding feel during scrolling, gaming and everyday operation.
Protection should not make the display look dull.
The super tough screen protector is designed with improved light transmittance, allowing the original color, brightness and detail of the phone display to remain clearly visible.
Whether users are viewing photos, watching videos, reading text or using the phone outdoors, the screen remains bright and natural.
A good screen protector depends on accurate dimensions.
The glass shape, edge profile, screen opening and overall size are carefully matched to the corresponding device to improve installation accuracy and compatibility.
This helps reduce common fitting problems such as:
- Misaligned edges
- Incorrect openings
- Oversized glass
- Unnecessary screen gaps
- Poor case compatibility
From reinforced edges to high-impact resistance, every part of the protector is designed around real everyday use.
The double-strengthened glass provides the structural durability needed for protection, while the plasma oleophobic coating and high-transparency glass preserve the smooth, clear experience of the original phone screen.
