Product Overview
The 3M VHB Tape 4910 is engineered for high-performance bonding across various high surface energy (HSE) substrates. Its unique acrylic foam core provides excellent strength, viscoelasticity, and adhesion, making it suitable for demanding applications.
Key Features:
- Long-Term Durability: Offers a fast and easy-to-use all-acrylic bonding method that gives immediate handling strength — no need to wait for curing.
- Smooth and Seamless: With a thickness of 40 mil (1.0 mm), this tape is designed as an alternative to mechanical fasteners, such as rivets, welds, and screws, or liquid adhesives.
- Versatile Applications: Adheres to a variety of high surface energy (HSE) substrates with minimal surface preparation.
- Reduce Steps: Can help increase operational efficiency by eliminating actions, such as drilling, welding, grinding, and finishing work.
- A Go-To Solution: Excels across a variety of markets, including window and door assembly, electronics, signage, construction, general industrial, and more.
- High-Temperature Resistance: Offers excellent indoor and outdoor performance, withstanding long-term use at a temperature up to 200 °F (93 °C) and short-term applications at 300 °F (149 °C).
- Excellent Bonding and Sealing: Featuring closed-cell acrylic chemistry, which creates a tight seal against water and moisture.
- Achieve More: Allows for the use of thinner, lighter-weight, and dissimilar materials when compared to rivets and welds.

Setup and Application
Proper surface preparation is crucial for optimal adhesion. Ensure surfaces are clean, dry, and free of oil, grease, dust, and other contaminants. For best results, use an appropriate surface cleaner.
Application Steps:
- Surface Preparation: Clean and dry all surfaces thoroughly before tape application.
- Tape Application: Apply the 3M VHB Tape firmly to one surface, ensuring good contact across the entire length.
- Liner Removal: Carefully peel off the red protective liner to expose the adhesive.
- Bonding: Align the second surface and press it firmly onto the tape, applying even pressure to ensure maximum contact and bond strength.
- Curing: The tape provides immediate handling strength, with full bond strength developing over 72 hours.

It highlights the ease of application, immediate bonding, and the tape's ability to create a strong, waterproof seal without the need for screws or rivets, improving efficiency and product aesthetics.
Operating Guidelines
Once applied, 3M VHB Tape 4910 forms a permanent bond. It is designed to withstand a wide range of temperatures, making it suitable for diverse environments. For optimal performance, ensure the tape is applied within the recommended temperature range (typically 60°F to 100°F or 15°C to 38°C for initial application, though it performs well in a broader range once bonded).
Maintenance
3M VHB Tape 4910 requires minimal maintenance once applied. For unused tape, store it in its original packaging in a cool, dry place, away from direct sunlight and extreme temperatures, to preserve its adhesive properties.
Troubleshooting
Common Issues:
- Difficulty peeling backing: Ensure a sharp edge or corner is used to initiate the peel. If the liner is tearing, try scoring it lightly with a utility knife (without cutting the tape) to create a starting point.
- Poor adhesion: Verify surfaces are clean, dry, and free of contaminants. Ensure sufficient, firm pressure is applied during application to maximize adhesive contact. Adhesion can be affected by surface energy; ensure the substrate is compatible with VHB tape.
- Water leakage: While the tape is designed for water sealing, improper application can lead to leaks. Re-evaluate the application process to ensure full contact, no air bubbles, and proper sealing along all edges.
