Long Description
Avery Dennison™ FT 7512 is a double-coated tissue tape engineered for superior dimensional stability and ease of handling, die cutting, and laminating. The tape features a very aggressive, strong permanent acrylic adhesive that provides high adhesion to a wide range of substrates, including foams, felts, non-woven materials, and other fibrous surfaces. It is ideal for applications where reliable, high-tack adhesion is critical, offering strong peel adhesion, initial tack, and excellent bonding performance.
This product is designed for easy removal at the point of application, providing convenience and flexibility in use, with a polyethylene-coated release liner that ensures consistent performance and smooth handling.
Key Features:
Very Aggressive, Strong Permanent Acrylic Adhesive:
FT 7512 utilizes a high-performance, modified acrylic adhesive that delivers high initial tack and peel adhesion, ensuring a secure bond on various foam, felt, fibrous, and non-woven materials.
Tissue Carrier:
The tissue carrier offers dimensional stability, improves handling during processing, and facilitates die cutting and lamination applications, providing flexibility and control in manufacturing.
Polyethylene Coated Release Liner:
The poly-coated Kraft liner ensures consistent release properties, reducing the risk of contamination and offering ease of handling and application, particularly when working with delicate substrates or intricate die-cut designs.
Controlled Adhesive Thickness:
The adhesive is engineered to offer controlled thickness, which enhances the adhesion performance and contributes to the overall tape quality in a variety of applications.
Easy Removal:
The tape is designed for clean and easy removal from the substrate at the point of application, minimizing adhesive residue and ensuring a high-quality final product.

Application Techniques:
Surface Preparation:
To achieve optimal adhesive bonding, ensure that the application surface is clean, dry, and free from contaminants such as grease and oil.
Adhesive Bond Strength:
Bond strength is heavily dependent on the amount of adhesive-to-surface contact. Therefore, it is important to apply the tape with consistent pressure and maintain proper temperature and time conditions to maximize performance.
Die Cutting and Laminating:
The tissue carrier provides excellent dimensional stability and is ideal for die-cutting and laminating operations. The controlled adhesive thickness ensures consistent, reliable performance during these processes.
Storage and Shelf Life:
Shelf Life:
FT 7512 is designed for two years of shelf life when stored under proper conditions.
Storage Conditions:
To maintain optimal performance, store the tape at 64-72°F (18-22°C), with 30-70% relative humidity, and keep it out of direct sunlight. The tape should be stored in its original packaging to prevent contamination and damage.
Applications:
Foam and Felt Bonding:
FT 7512 is ideal for bonding foam, felt, and fibrous materials, making it suitable for applications in industries such as automotive, furniture, and packaging.
Component Mounting:
The tape is commonly used in component mounting where high adhesion and dimensional stability are critical, such as in the assembly of electronics, appliances, and consumer goods.
Die-Cutting and Laminating:
Its high stability and controlled adhesive thickness make it perfect for die-cutting and laminating applications in printing and labeling industries.
Conclusion:
Avery Dennison™ FT 7512 is a high-performance double-coated tissue tape that offers excellent dimensional stability, strong adhesion, and easy application for a wide variety of foam, fibrous, and non-woven materials.
