Benefits
Permanent Bonding
5604A-GP provides a permanent adhesive bonding method that can simplify assembly and reduce dependence on conventional fasteners.
Thin Bond Line
With a nominal thickness of 0.4 mm, the tape provides a low-profile bonding solution for assemblies where space and appearance are important.
Mechanical Fastener Replacement
In suitable applications, 5604A-GP can replace rivets, screws, bolts and spot welding, helping simplify assembly and reduce the need for drilling or welding operations.
Stress Distribution
The acrylic foam construction distributes bonding forces over a larger area, helping reduce localized stress concentrations.
Vibration Absorption
The foam core can help absorb vibration and accommodate normal movement between bonded components.
Sealing Capability
The continuous adhesive layer can help provide a sealing function while bonding components, making it suitable for applications where attachment and sealing are required together.
Cost-Effective VHB Solution
5604A-GP is positioned as a cost-conscious entry-level VHB product while maintaining the benefits of acrylic foam bonding technology.

Installation Guide
1. Clean the Surface
Remove dust, oil, grease, moisture and other contaminants from the bonding surfaces.
2. Prepare the Substrate
Make sure the bonding surfaces are clean, dry and suitable for acrylic adhesive bonding.
For painted, coated or difficult-to-bond surfaces, evaluate the actual substrate and coating before production.
3. Apply the Tape
Apply 5604A-GP smoothly to the first substrate.
Avoid stretching the tape during application.
4. Apply Pressure
Apply firm and uniform pressure across the tape to maximize adhesive contact with the substrate.
5. Remove the Liner
Remove the liner carefully without touching or contaminating the exposed adhesive.
6. Assemble the Components
Position the second component accurately and bring it into contact with the exposed adhesive.
7. Allow Bond Development
Acrylic pressure-sensitive adhesive develops its final bond progressively. Avoid applying excessive loads immediately after assembly unless the application has been validated.
8. Test the Finished Assembly
For critical applications, evaluate peel, shear, vibration, temperature, humidity, weathering and aging performance under actual service conditions.
Storage
Store 3M™ VHB™ Tape 5604A-GP in its original packaging in a clean, dry environment.
Recommended storage practices:
- Keep the tape in its original packaging.
- Protect from direct sunlight.
- Avoid excessive heat and humidity.
- Protect the adhesive from dust and contamination.
- Avoid crushing, bending or deforming rolls.
- Follow the latest applicable 3M storage recommendations.
For long-term storage and shelf-life requirements, always refer to the latest applicable 3M technical documentation.

Yes, when the plastic has suitable surface energy and has been properly prepared. Low-surface-energy plastics such as PP and PE require specific evaluation before use.
Can 5604A-GP be die-cut?
Yes. Acrylic foam tape can be converted into custom shapes, strips, pads and die-cut components depending on the selected tape and liner configuration.
What is the difference between 5604A-GP and 5604A-GF?
Both are 0.4 mm gray 5604A-family products, but the GP configuration is positioned as the general-purpose/entry-level configuration. The exact construction, liner and commercial configuration should be confirmed against the applicable 3M product documentation.
What is the difference between 5604A-GP and 5604A-WP?
The main visible difference is the product color/configuration:
- 5604A-GP: Gray
