3M™ VHB™ Tape 4930 White
Code: 3M 4930 / 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.
- White Colour: The white colour provides a clean appearance and is often chosen 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 a clean appearance are required.
- Construction: Attaching architectural panels, trim, and other building components. The tape's ability to withstand environmental stresses makes it suitable for construction applications.
- Automotive: Bonding trim, emblems, and other automotive components. The tape's strength and durability make it suitable for use in vehicles.
- Electronics: Securing components and assemblies in electronic devices, where reliable bonding and temperature resistance are essential.
- Industrial: Bonding metal, glass, and plastic components in various industrial applications.
Specifications
- Colour: White
- Thickness: Typically around 1.1 mm (45 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
- Surface Preparation: Clean surfaces thoroughly to remove any dust, grease, or contaminants. Use isopropyl alcohol or a suitable surface cleaner.
- Application:
- Cut the tape to the desired length.
- Apply the tape to one surface, pressing firmly to ensure good contact.
- Remove the liner and apply the second substrate, using pressure to secure the bond.
- 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™ 4930 VHB Tape White is an excellent choice for applications requiring strong, durable bonds with a clean appearance. Its high temperature resistance, conformability, and ease of application make it suitable for a wide range of industries, including signage, construction, automotive, electronics, and industrial.
