How to achieve high adhesion and long lifespan of touch screen adhesive backing?
May 27, 2025
In touch screen manufacturing, adhesive backing is a key auxiliary material that directly affects the sealing, shock resistance, and service life of the screen. Taking Shenzhen Xinlilai Touch Technology Co., Ltd' s touch screen adhesive as an example, its key lies in the combination of structural design and material science.
1. Innovative structural design: filling gaps and improving sealing performance
Traditional adhesive tape often adopts a flat box structure, but the tolerance between the chassis and the touch screen can easily lead to gaps, affecting waterproof performance. Xinlilai effectively fills gaps and enhances sealing effects through the "extension" and top protrusion design of resin board extension, especially suitable for products with large dimensional tolerances.
2. High performance adhesive: The dual advantages of acrylic adhesive
The upper and lower adhesives of the backing are made of acrylic material, which combines high initial adhesion and long-term stability. Test data shows that the adhesive strength of acrylic adhesive on surfaces such as glass and metal can reach 9-10 N/cm, and the strength remains stable after 14 days, far exceeding industry standards. In addition, the temperature resistance of acrylic adhesive (short-term 90 ° C, long-term 70 ° C) can meet the operational requirements of equipment in high-temperature environments.
3. Emphasize both environmental protection and safety
Xinlilai adhesive uses solvent-free and environmentally friendly materials, certified by SGS, and does not contain harmful substances such as formaldehyde. It is suitable for fields with extremely high safety requirements such as medical equipment. For example, a medical device manufacturer used this type of adhesive to fix the internal components of a blood glucose meter, which successfully passed the vibration test without any volatile release.
Summary: Through structural optimization and material upgrades, Xinlilai adhesive for touch screen has achieved breakthroughs in bonding strength, environmental adaptability, and safety, providing reliable guarantees for touch screen.
