Long Description
Avery Dennison™ AFB™ 6264B is a black acrylic foam tape that features double-coated modified acrylic adhesive on both sides of a viscoelastic foam carrier. This tape is designed for applications requiring high adhesion, excellent shear strength, and resistance to UV light and elevated temperatures. It bonds well to a variety of medium to low surface energy materials, including many powder-coated paints and plastics, making it ideal for office furniture, telecommunication mounting, TV frame mounting, and decorative applications. Its closed-cell structure and viscoelastic properties allow it to absorb shock and distribute stress evenly, making it suitable for environments with vibration or movement.
Key Features:
Double-Coated Modified Acrylic Adhesive:
The tape features high-performance acrylic adhesive on both sides, offering strong initial adhesion and long-lasting bonding to a variety of substrates, including medium to low surface energy paints and plastics.
Viscoelastic Foam Carrier:
The foam core of AFB™ 6264B is viscoelastic, providing a unique combination of high adhesion and good shear strength. This allows the tape to absorb shock and distribute stress evenly, which is particularly useful in applications that experience vibration or other forces.
Closed-Cell Structure:
The tape's closed-cell foam structure contributes to moisture resistance, UV stability, and high temperature resistance, making it suitable for both indoor and outdoor applications.
Uniform Bonding Performance:
The modified acrylic adhesive system provides consistent performance in terms of adhesion and shear strength, ensuring reliable bonding over time.
Eliminates Mechanical Fasteners:
AFB™ 6264B helps reduce the need for mechanical fasteners such as screws, bolts, or rivets. By replacing traditional fasteners, this tape eliminates the need for drilling or grinding and minimizes cleanup after installation.
Polyethylene Liner:
The red polyethylene liner offers moisture stability and makes handling easier due to its high tear strength. This liner ensures that the adhesive is protected until the point of application, preserving the integrity of the bond.

Application Techniques:
Surface Preparation:
For best results, ensure that the surface is clean, dry, and free of any contaminants like grease or oil. The bond strength will be directly affected by the surface condition.
Bonding Process:
Apply the tape under consistent pressure to achieve maximum adhesive-to-surface contact. Bond strength is also influenced by temperature, pressure, and time, so ensure optimal conditions during application for the best results.
Eliminating Mechanical Fasteners:
By using AFB™ 6264B, you can avoid the need for drilling or grinding, which can cause surface damage or require additional cleanup.
Storage and Shelf Life:
Shelf Life:
AFB™ 6264B is designed for a one-year shelf life when stored properly.
Storage Conditions:
Store the tape in a cool, dry place at 64-72°F (18-22°C) with 30-70% relative humidity. Keep the tape out of direct sunlight and in its original packaging to preserve adhesive properties and ensure optimal performance.
Applications:
Office Furniture:
Ideal for furniture mounting, including the bonding of panels, trims, and other components in office settings.
Telecommunication:
AFB™ 6264B can be used for mounting and securing telecommunication equipment like routers and cables, offering a strong, reliable bond without the need for screws.
TV Frame Mounting:
Perfect for TV frame mounting, where the tape provides a secure bond while maintaining a clean appearance with no visible fasteners.
Decorative and Display Applications:
The tape is suitable for decorative mounting in consumer goods and display fixtures, offering consistent strength and resistance to environmental factors like UV light and high temperatures.
Automotive and Industrial Applications:
The tape can be used in automotive or industrial settings where strong, reliable adhesion is necessary on surfaces such as plastics, metals, and composite materials.
Conclusion:
Avery Dennison™ AFB™ 6264B is a high-performance black acrylic foam tape offering strong adhesion, excellent shear strength, and outstanding resistance to UV, moisture, and high temperatures. Its viscoelastic foam carrier provides shock absorption and stress distribution, making it ideal for office furniture mounting, telecommunication applications, decorative mounting, and more. The tape's double-coated acrylic adhesive and closed-cell foam structure ensure reliable bonding in both indoor and outdoor applications, while eliminating the need for traditional mechanical fasteners.
