Tesa 68646 Double-Sided Non-Woven Tape | 0.14mm Acrylic Adhesive Tape

Benefits

Reliable Adhesion

Provides strong adhesion on selected plastic, metal, glass and foam surfaces.

Thin Tape Construction

The 140 μm thickness supports applications requiring a relatively thin adhesive layer.

Versatile Material Lamination

Suitable for selected foam and felt lamination processes and component mounting applications.

Environmental Resistance

Offers very good humidity and UV ageing resistance, together with good chemical resistance under suitable conditions.

Efficient Converting

The tape’s good converting properties support slitting and other customized processing operations.

High Initial Tack

Very good tack helps facilitate positioning and bonding during assembly.

Technical Specifications

Typical Adhesion Values

Technical note: These are representative or typical values and should not be treated as product specifications. Actual performance depends on the substrate, surface preparation, bonding pressure, dwell time and operating conditions.

Installation Guide

1. Surface Preparation

• Ensure bonding surfaces are clean, dry and free from dust, oil and contaminants.
• Remove loose particles and release agents.
• Check whether the substrate requires special treatment.

2. Tape Application

• Cut the tape to the required size.
• Apply the tape evenly to the first substrate.
• Avoid wrinkles, air pockets and contamination.
• Remove the liner carefully.
• Align and apply the second substrate.

3. Pressure Application

• Apply uniform pressure across the bonding area.
• Ensure sufficient adhesive contact.
• Avoid excessive tension during application.

4. Performance Evaluation

• Allow suitable dwell time before applying significant loads.
• Evaluate peel adhesion and shear resistance.
• Conduct application-specific testing before mass production.

Storage

• Store the tape in its original packaging.
• Keep it in a clean and dry environment.
• Protect it from direct sunlight and contamination.
• Avoid excessive heat and humidity.
• Follow the latest applicable tesa storage recommendations.

Shelf life and detailed storage conditions should be confirmed with the relevant product documentation.
