Benefits
Permanent Bonding
5604A-GF provides a durable bonding solution for suitable substrates and can reduce the need for conventional mechanical fastening.
Thin Profile
The 0.4 mm thickness provides a low-profile bond line for assemblies where space and appearance are important.
Stress Distribution
The acrylic foam construction helps distribute stress across the bonded area, reducing localized stress concentrations compared with point fastening methods.
Conformability
The foam core can conform to minor surface irregularities, helping increase adhesive contact with suitable substrates.
Clean Appearance
The gray construction provides a consistent industrial appearance and eliminates exposed screws, rivets and other mechanical fasteners.
Simplified Assembly
Tape bonding can reduce drilling, riveting and other secondary assembly operations when the application is appropriately designed and validated.

3M identifies the 5604A family as a thin acrylic foam tape designed for general-purpose bonding applications, including bonding and sealing of suitable metal components and other high-surface-energy substrates.
Technical note: Actual adhesion and durability depend on the substrate, surface preparation, bond area, load, temperature, environmental exposure and application design. Always confirm the latest applicable 3M technical documentation before specifying the tape for critical applications.
Applications
3M™ VHB™ Tape 5604A-GF can be used for:
- Metal component bonding
- Metal panel assembly
- Nameplate and badge attachment
- Decorative trim attachment
- Sign and display assembly
- Electronic equipment assembly
- Appliance component bonding
- Interior and exterior trim
- Reinforcement attachment
- Panel-to-frame bonding
- Plastic component assembly
- Industrial equipment assembly
- General manufacturing applications
The 5604A family can be considered where bonding and sealing are required simultaneously or where conventional mechanical fastening methods may be replaced by adhesive bonding.
Compatible Materials
5604A-GF is primarily intended for suitable high-surface-energy substrates, including:
- Aluminum
- Stainless steel
- Steel
- Painted metal
- Glass
- Acrylic
- ABS
- Other suitable high-surface-energy plastics
- Painted or coated surfaces with adequate surface energy
For low-surface-energy plastics such as polypropylene (PP) and polyethylene (PE), reliable adhesion should not be assumed. Surface treatment, primer or a different adhesive technology may be required.
Always conduct application-specific testing before production.

Installation Guide
1. Clean the Surface
Remove dust, oil, grease, moisture and other contaminants from the bonding surfaces.
2. Prepare the Substrate
Ensure that the substrate is dry, clean and suitable for acrylic adhesive bonding. Coated, painted or difficult-to-bond surfaces should be evaluated before production.
3. Apply the Tape
Apply 5604A-GF smoothly to the first substrate. Avoid stretching the tape during application.
4. Apply Firm Pressure
Apply sufficient and uniform pressure across the tape to establish intimate contact between the adhesive and substrate.
5. Remove the Liner
Remove the release liner without contaminating the exposed adhesive.
6. Assemble the Components
Align the second component carefully and bring it into contact with the adhesive.
7. Allow Adhesion to Develop
Avoid excessive loading immediately after assembly. Acrylic adhesive performance develops over time.
8. Validate the Application
For production applications, test the finished assembly under the expected temperature, humidity, vibration, shear, peel and aging conditions.
Storage
Store 3M™ VHB™ Tape 5604A-GF in its original packaging under clean and dry conditions.
Recommended storage practices:
- Keep the product in its original packaging.
- Protect from direct sunlight.
- Avoid excessive heat and moisture.
- Keep adhesive surfaces clean and protected.
- Do not store rolls where they can be crushed or deformed.
- Follow the latest applicable 3M storage and shelf-life recommendations.
For long-term storage, refer to the current 3M technical documentation supplied with the specific product configuration.
FAQ
What is 3M 5604A-GF?
3M™ VHB™ Tape 5604A-GF is a 0.4 mm gray double-sided acrylic foam tape designed for permanent bonding and assembly applications.
What does GF mean in 5604A-GF?
5604A-GF identifies a specific gray configuration of the 3M™ VHB™ 5604A family. The gray appearance makes it suitable for many industrial assemblies where a gray bond line is acceptable or preferred.
How thick is 5604A-GF?
The nominal thickness is 0.4 mm (0.016 in).
Is 5604A-GF double-sided?
Yes. It is a double-sided acrylic pressure-sensitive adhesive tape designed for permanent bonding.
What materials can 5604A-GF bond?
It is primarily designed for suitable metals and other high-surface-energy substrates. Actual adhesion depends on the substrate and surface condition.
Can 5604A-GF replace screws and rivets?
In suitable applications, yes. Acrylic foam tape can distribute the bonding load over a larger area and may replace certain mechanical fastening methods when the application is properly engineered and tested.
Can 5604A-GF be used on plastic?
Yes, provided the plastic has suitable surface energy and the application has been validated. Low-surface-energy plastics such as PP and PE generally require additional surface preparation or an alternative bonding solution.
Can 5604A-GF be die-cut?
Yes. The material can be converted into custom shapes such as strips, pads, rings and precision die-cut parts, depending on the selected tape and liner configuration.
Is 5604A-GF suitable for outdoor use?
Outdoor suitability depends on the specific application, substrate, load and environmental exposure. The actual assembly should be tested under expected service conditions before outdoor production use.
What is the difference between 5604A-GF and 5604A-WP?
The key visible difference is color:
- 5604A-GF: Gray
- 5604A-WP: White
Both are 0.4 mm products in the 5604A family. Select the appropriate version according to appearance, substrate, converting requirements and application conditions.
