3M™ VHB™ Tape 4920 is a double-sided tape comprised of a general-purpose acrylic adhesive with a firm, foam core that delivers a total thickness of 15 mil (0.4 mm) when applied and requires no fixturing or curing time. Engineered to be strong, it can replace rivets, welds, and screws while providing faster production by eliminating the need for drilling, welding, grinding, and project cleanup. Offering seamless joining and minimal surface preparation, this easy-to-use bonding method keeps surfaces smooth and enhances the appearance of applications involving thin, lightweight, and dissimilar materials. Providing adhesion to a broad range of materials from metals, glass, and other high surface energy substrates, the advanced closed-cell acrylic technology provides secure bonding that protects against water and seals tightly for long-term durability. It performs in applications for short-term use (up to four hours) at a temperature up to 300 °F (149 °C) or long-term use withstanding up to 200 °F (93 °C). These attributes make 3M™ VHB™ Tape 4920 a reliable choice to take on a variety of bonding and sealing applications in transportation, signage, displays, general industrial, appliance, and electronics. Discover the many ways to apply the powerful bonding potential of 3M™ VHB™ Tape 4920.

Convenience Meets Extreme Bonding Power
Our 3M™ VHB™ Tape consists of a durable acrylic adhesive with viscoelastic properties. This provides an extraordinarily strong double sided foam tape that adheres to a broad range of high surface energy (HSE) substrates, including aluminum, stainless steel, galvanized steel, composites, acrylic, polycarbonate and painted or sealed wood and concrete. Our bonding tapes provide excellent shear strength, surface adhesion, durability and temperature resistance. Applications for this tape include stiffener bonding and panel and trim attachment.

3M VHB Tape 4920 is an excellent choice for stiffener to panel applications

An Unconventional Foam Tape
We invented 3M™ VHB™ Tapes in 1980 as the first of their kind. These unique tapes combine conformability with a strong, permanent bond. The result is a family of extraordinarily strong tapes that adhere to a broad range of substrates. 3M™ VHB™ Tape is a proven alternative to screws, rivets, welds and other forms of mechanical fasteners. Skyscrapers, cell phones, electronic highway signs, refrigerators, architectural windows and more all rely on this specialty bonding tape for one or more steps in the assembly, mounting, fastening and sealing process. This trusted and reliable tape offers a consistent bond, outstanding durability and excellent solvent and moisture resistance. 3M stands by all of its products and is there to provide you with design guidance and technical support when you need it.

Proven Reliability from 3M™ VHB™ Tapes
3M™ VHB™ Tape offers a durable bond in a way that mechanical fasteners can't. This tape enhances the appearance of finished goods by eliminating rivets and screws while providing immediate handling strength. In most cases, fastening with 3M™ VHB™ Tape is a quicker process than drilling, fastening, or using liquid adhesive. This versatile line of tapes can be used indoors or outdoors in a variety of applications, including window, door and sign assembly, electronics, construction and countless other industrial applications. Chemically resistant as well as UV and temperature stable, 3M™ VHB™ Tape can withstand the heat of Dubai to the cold of Canada. The unique acrylic chemistry is extremely durable and resistant to change over time, making this a long-lasting and powerful tape you can trust.
