Long Description
Avery Dennison™ FT 7354DL is a 200-micron double-coated film tape featuring a modified acrylic adhesive system and a clear PET carrier. Designed primarily for component mounting in mobile phone assembly, this tape offers superior adhesion and performance for applications that require high dynamic shear strength, resistance to UV light, and excellent cohesion. The dual clear PET release liners provide ease of handling and application, while the tape's specially formulated adhesive ensures a secure bond on a wide range of substrates, including low surface energy materials.
Key Features:
Modified Acrylic Adhesive: The modified acrylic adhesive provides high adhesion and excellent performance on various substrates, including low surface energy materials such as plastics and rubbers.
Clear PET Carrier: The transparent polyester (PET) carrier ensures high dimensional stability, optical clarity, and minimal visibility of the tape, making it ideal for applications where aesthetics and transparency are important.
Dual Clear PET Release Liners: The tape is protected by two clear PET release liners, ensuring smooth handling and easy removal during the application process. This feature also reduces the risk of contamination during storage and use.
Benefits:
High Adhesion on a Variety of Substrates:
FT 7354DL provides exceptional adhesion to a wide range of surfaces, including challenging low surface energy materials, making it ideal for component mounting in mobile phone and other electronic devices.
Excellent Cohesion for High Dynamic Shear:
The tape’s modified acrylic adhesive offers superior cohesion, providing high dynamic shear strength and push-out force resistance, which is essential in applications where long-term durability and stability are critical.
Temperature and UV Resistance:
FT 7354DL has excellent resistance to high temperatures (up to 212°F / 100°C) and UV light, making it suitable for applications in harsh environments, such as outdoor or automotive components, or where the tape is exposed to sunlight for extended periods.
Reduced Risk of Wrinkles and Contamination:
The tape’s smooth release system reduces the risk of wrinkles, shrinkage, and contamination from fibers or particles during application, ensuring a clean and precise bond.
Clean Handling:
With its dual PET release liners, the tape is easy to apply without risking damage or contamination. The transparent liners also provide enhanced visual control during the application process.

Application Techniques:
Surface Preparation:
To ensure optimal bond strength, the surface to which the tape is applied should be clean, dry, and free of grease, oil, and any other contaminants. Surface preparation is crucial to achieving strong adhesion.
Bonding Conditions:
The bond strength is influenced by the amount of adhesive-to-surface contact. Applying the tape with consistent pressure, time, and temperature will ensure optimal performance. Different surfaces (rigid or flexible) may require adjustments in application technique.
Handling and Storage:
Handle the tape carefully to prevent contamination and damage. It is recommended to apply the tape at room temperature for best performance.
Storage and Shelf Life:
Shelf Life:
The product has a shelf life of one year when stored under appropriate conditions.
Storage Conditions:
Store the tape in a cool, dry place (18-22°C / 64-72°F), with 30-70% relative humidity, and out of direct sunlight. Keep the product in its original packaging to maintain its performance characteristics.
Applications:
Mobile Phone Assembly: Ideal for component mounting and assembly in mobile phone manufacturing, providing secure bonding for delicate parts.
Electronics and Gadgets: Suitable for applications in electronics where high adhesion, UV resistance, and clean removability are essential.
Consumer Devices: Ideal for use in wearable devices, consumer electronics, and similar applications that require clean, reliable adhesion without the risk of contamination.
