3M™ 4910 VHB Tape Clear

3M 4910 VHB Tape Clear

Code: 3M 4910 / Category: VHB Foam Tapes

Features

  • High Bond Strength: Provides a strong, durable bond to a variety of surfaces, including metals, glass, and high surface energy (HSE) plastics.
  • Clear Color: The clear color provides a discreet appearance, suitable for applications where aesthetics are important.
  • Temperature Resistance: Designed to perform in a wide range of temperatures. It can withstand high temperatures, making it suitable for applications involving heat exposure.
  • Good Conformability: The foam core provides good conformability to irregular surfaces, ensuring a reliable bond.
  • Viscoelastic Properties: The tape's viscoelasticity allows it to absorb shock and distribute stress, improving the durability of the bond.
  • Ease of Application: The tape is easy to apply and can be cut to specific shapes and sizes to meet various application requirements.

Typical Applications

  • Signage: Mounting signs and displays, where high bond strength and clarity are required.
  • Electronics: Securing components and assemblies in electronic devices, where reliable bonding and temperature resistance are crucial.
  • Point-of-Purchase Displays: Bonding transparent elements in displays and fixtures, maintaining a clear appearance.
  • Automotive: Bonding transparent components in vehicle interiors or exteriors, maintaining visibility while providing strong adhesion.
  • Glass Bonding: Bonding glass panels, windows, and mirrors, providing a clear, durable bond.

Specifications

  • Color: Clear
  • Thickness: Typically around 1.0 mm (40 mils)
  • Temperature Resistance: Up to 93°C (200°F) for long-term exposure, short-term spikes up to 149°C (300°F)
  • Adhesive Type: Acrylic
  • Liner: Usually comes with a red polyethylene liner for easy handling and application

Usage Instructions

  1. Surface Preparation: Clean surfaces thoroughly to remove any dust, grease, or contaminants. Use isopropyl alcohol or a suitable surface cleaner.
  2. Application:
    1. Cut the tape to the desired length.
    2. Apply the tape to one surface, pressing firmly to ensure good contact.
    3. Remove the liner and apply the second substrate, using pressure to secure the bond.
  3. Curing Time: While the tape provides high initial tack, the bond strength increases over time. Full bond strength is typically achieved after 72 hours.

Storage and Handling

  • Store the tape in a cool, dry place away from direct sunlight.
  • Maintain storage temperature between 16°C to 27°C (60°F to 80°F) for optimal performance.

Safety Considerations

  • When applying the tape in high-temperature environments or using it in applications involving exposure to chemicals, follow all safety guidelines and use appropriate personal protective equipment (PPE).

Conclusion

The 3M 4910 VHB Tape Clear is an excellent choice for applications requiring strong, durable bonds with a clear appearance. Its high temperature resistance, conformability, and ease of application make it suitable for a wide range of industries, including signage, electronics, point-of-purchase displays, automotive, and glass bonding.
