Product Data Sheet

3M™ VHB™ Tape 4920 is a high-performance white double-sided acrylic foam tape engineered to provide durable, permanent bonding across a wide range of industrial and commercial applications. Featuring a 0.015 inch (0.4 mm) thick firm acrylic foam core, this tape delivers excellent strength, stability, and long-term performance when bonding high surface energy materials such as metals, glass, painted surfaces, and many plastics.

As part of the trusted 3M™ VHB™ 4950 family, this tape combines a general-purpose acrylic adhesive with a firm foam structure to create a reliable bonding solution that replaces mechanical fasteners like rivets, screws, and welds. It eliminates the need for drilling, grinding, or refinishing, while maintaining a smooth, professional appearance.

3M™ VHB™ 4920 provides immediate handling strength with its pressure-sensitive adhesive, while continuing to build bond strength over time for maximum performance. The firm foam core helps distribute stress evenly across the bond line, improving durability and allowing for the bonding of dissimilar materials. Additionally, it forms a strong seal against water, moisture, and environmental exposure, enhancing long-term reliability.

Designed to perform in demanding environments, this tape offers excellent temperature resistance, maintaining performance up to 300°F (149°C) short term and 200°F (93°C) long term. Its viscoelastic properties allow it to absorb vibration, accommodate thermal expansion, and maintain bond integrity under dynamic conditions.

Common applications include panel bonding, signage, metal fabrication, appliance assembly, and general manufacturing. For professionals seeking a clean, efficient, and high-strength bonding solution, 3M™ VHB™ Tape 4920 delivers proven performance, design flexibility, and long-lasting results.
