1. Product Overview
The tesa fix 4965 is a transparent, double-sided mounting tape featuring a polyester carrier and an acrylate adhesive system. It is designed for strong, reliable bonding across various surfaces, including plastics like ABS and EPDM, due to its high resistance to plasticizers. This tape is characterized by its temperature resistance and strong initial and long-term adhesion.
It is commonly used in applications such as mounting ABS parts in the automotive industry, self-adhesive fitting of rubber and EPDM profiles, strip bonding in the furniture industry, sealing insulating pipe shells, display and sign gluing, equipment of lead profiles, convertible top bonding, and endless bonding of aluminum sheets.

2. Setup and Preparation
Proper surface preparation is crucial for optimal adhesion. Follow these steps before applying the tape:
- Clean Surfaces: Ensure all surfaces to be bonded are clean, dry, and free from dust, dirt, oil, grease, and other contaminants. Use an appropriate cleaning agent if necessary, and allow surfaces to dry completely.
- Temperature: For best results, apply the tape at room temperature, ideally between 15°C and 25°C (59°F and 77°F). Extreme temperatures can affect initial tack and final bond strength.
- Surface Smoothness: While the tape offers strong adhesion, extremely rough or porous surfaces may require additional preparation or a primer for maximum bond strength.
3. Operating and Application
Follow these instructions for applying tesa fix 4965 tape:
- Cut to Length: Cut the desired length of tesa fix 4965 tape from the roll.
- Apply to First Surface: Apply the tape firmly to one of the surfaces to be bonded. Ensure even pressure across the entire length of the tape.
- Remove Liner: Carefully peel off the red protective liner to expose the second adhesive side.
- Position and Bond: Align the second surface precisely with the tape. Once positioned, press the two surfaces together firmly and evenly along the entire bonded area. Apply consistent pressure for several seconds to ensure good initial contact.
- Curing Time: While initial tack is strong, the adhesive will reach its full bond strength over time. Allow 24-72 hours for the adhesive to fully cure, especially for critical applications.
4. Maintenance and Storage
To maintain the quality and performance of tesa fix 4965 tape:
- Storage: Store the tape in its original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. Ideal storage conditions are typically between 10°C and 30°C (50°F and 86°F) with relative humidity between 40% and 70%.
- Shelf Life: Adhesives can degrade over time. Refer to the product packaging or manufacturer's guidelines for specific shelf life recommendations.
- Handling: Avoid touching the adhesive surface with bare hands to prevent contamination from oils and dirt, which can reduce adhesion.
5. Troubleshooting
If you experience issues with adhesion, consider the following common causes and solutions:
- Poor Adhesion:
- Cause: Insufficient surface cleaning. Solution: Ensure surfaces are thoroughly cleaned and dried before application.
- Cause: Incorrect application temperature. Solution: Apply tape within the recommended temperature range (15°C - 25°C).
- Cause: Insufficient pressure during application. Solution: Apply firm, even pressure across the entire bonded area.
- Cause: Incompatible surface material. Solution: While tesa fix 4965 is versatile, some low-surface-energy plastics may require a primer.
- Tape Not Sticking Evenly:
- Cause: Uneven surface or trapped air bubbles. Solution: Ensure surfaces are as flat as possible. Apply tape slowly and press out any air bubbles.
