3M™ VHB™ Tapes replace rivets, spot welds, liquid adhesives and other permanent fasteners for providing a robust and durable bond to a wide range of applications. 3M™ VHB™ Tapes achieve durability by absorbing energy from the foam core and allowing movement, rather than fighting it. For both dynamic and static stress conditions they bond with high adhesion. From traffic sign panels to stiffeners, from building panels to frames, and from panels, stiffeners to trims on trucks, trailers, signs and other applications – 3M VHB Tapes bond almost anything.

3M™ VHB™ Tapes have passed crash test requirements for both the 20 and 60 miles per hour (32 and 98 kilometers per hour) speed categories. After the crash test was performed all stiffeners and batten strips attached with 3M™ VHB™ Tapes were intact.

A traffic-sign bonded with 3M™ VHB™ Tapes was tested with static load to simulate the wind shear. The test concluded that these tapes were acceptable according to the 1985 AASHTO Standards at wind speeds of 145 km/hr (90 miles per hour). On testing with a 240 kg load (simulating 260 km/hr or 160 mph wind shear) the steel U-post deformed, but the adhesive bond between the aluminum sign panel and the stiffeners were intact.

The Louisiana Department of Transportation (DOT) conducted tests for both the static and dynamic load performance of acrylic foam tapes in highway signs. They placed an experimental sign built with 3M™ VHB™ Tapes before 1992. In 1992, Hurricane Andrew generated winds of up to 250 km/hr (155 mph) in the Baton Rouge area, destroying several signs constructed using rivets and bolts, but the test sign constructed with acrylic foam tape endured these speeds.

Both crash impact and static load tests have been performed by the Safety and Structural Systems Division of the Texas Transportation Institute at Texas A&M, according to the National Cooperative Highway Research Program Report (NCHRP) 230 and the 1985 American Association of State Highway and Transportation Officials (AASHTO) Guide, Standard Specifications for Structural Supports for Highway Signs, Luminaries and Traffic Signals.

3M VHB Tapes were tested on construction panels and wind load structural tests of 120 lb/ft2 (5.7 kPa), which corresponds to a sustained wind speed of 220 mph (350 kph). It passed all the tests and also wind load structural tests of 60 lb/ft2 (2.9 kPa) performed at temperatures ranging from -20°F (-29°C) to 150°F (66°C) and hurricane impact & pressure cycling tests with a building design pressure of up to 60 lb/ft2 (2.9 kPa)

Tests performed by the Construction Research Laboratory (Miami, FL) are according to the ASTM E330 Standard Test Method for Structural Performance of Exterior Windows, Curtain Walls and Doors by Uniform Static Air Pressure Difference and ASTM E1996 – the "Standard specification for Performance of Exterior Windows, Curtain Walls, Doors and Storm Shutters Impacted by Windborne Debris in Hurricanes".
Architectural metal panels Architectural metal panels that are assembled with 3M™ VHB™ Tapes demonstrated excellent performance in demanding tests, which provides strong evidence of durability and also indicates that these tapes meet performance standards of the construction industry.
