Why Choose tesa 6304
Tesa 6304 is a strong candidate when you need to bond low-surface-energy substrates without relying on a primer. Its high-performance LSE adhesive is designed to create an efficient and secure bond, while its viscoelastic acrylic foam core helps manage dynamic and static loads.
The multiple thickness options also allow engineers to select a suitable construction for different mounting and gap-management requirements.
For OEM applications, Yousan can support slitting, rewinding, laminating, precision die-cutting, custom pads, strips, and other adhesive tape converting solutions.
Installation Guide
- Prepare the surfaces: Remove dust, oil, grease, moisture, and other contaminants.
- Check the substrates: Confirm that the materials are compatible with the LSE adhesive.
- Clean the bonding area: Use an appropriate cleaning method for the substrate.
- Cut the tape: Select the appropriate width, length, or die-cut shape.
- Apply the tape: Apply evenly without stretching the acrylic foam tape.
- Apply pressure: Press firmly across the bonding area to improve adhesive contact.
- Remove the liner: Carefully remove the PE release liner.
- Position the component: Align the second substrate accurately.
- Apply pressure: Press the substrates together firmly and evenly.
- Allow bonding time: Avoid excessive loading immediately after assembly and allow the adhesive to build its required bonding performance.
Storage
Store tesa 6304 in its original packaging in a clean and dry environment. Protect the tape from direct sunlight, excessive heat, moisture, dust, and contamination.
For long-term storage, follow the latest official tesa storage and shelf-life recommendations for the specific product configuration.
FAQ
Q1: What is tesa 6304?
tesa 6304 is a gray double-sided acrylic foam tape with a high-performance LSE adhesive designed for permanent mounting applications.
Q2: What does LSE mean?
LSE stands for Low Surface Energy. LSE materials can be more difficult to bond than high-surface-energy materials. tesa 6304 uses a high-performance LSE adhesive designed to improve bonding to such substrates.
Q3: Can tesa 6304 eliminate primer?
Its LSE adhesive can help eliminate the need for primer in suitable applications. However, the actual application should be tested before primer is removed from an established bonding process.
Q4: What thicknesses are available for tesa 6304?
The official product information lists 500 μm, 640 μm, 800 μm, 1100 μm, and 1500 μm formats in addition to the 400 μm standard technical configuration.
Q5: Is tesa 6304 suitable for plastic bonding?
Yes. Plastic panel mounting is one of the example applications specified by tesa.
Q6: Is tesa 6304 suitable for glass?
Yes. tesa lists decorative glass panel mounting as an example application.
Q7: What is the temperature resistance of tesa 6304?
The current technical information lists a short-term temperature resistance of 120°C. The suitability for a specific application depends on temperature duration, load, substrate, and environmental conditions.
Q8: Can tesa 6304 be die-cut?
It can be considered for adhesive tape converting applications such as slitting, rewinding, laminating, and precision die-cutting, subject to the required geometry and processing conditions.
