3M VHB tape for durable bonds

3M VHB is a family of high-strength double-sided acrylic tapes for durable bonds. It can allow components to be joined without visible screws or rivets and distributes loads across the bonded area. The suitable variant depends on the materials, surface and loads in the specific joint. The range includes different tape constructions and variants as well as accessories for surface preparation.

Choose a clear variant when a bond should be unobtrusive in a visible area. 3M identifies suitable VHB tapes for clear materials, and the product catalogue includes a clear variant. Also check the materials, required tape thickness and the appearance of the joint edge on the component. Clear appearance alone does not establish that a tape will bond to every plastic or withstand every load.

The actual temperature profile, the materials being joined and the production process are decisive. 3M describes the GPH family for high-temperature applications and for joining dissimilar materials. That does not amount to a blanket temperature approval for every VHB tape. Specify the duration and type of exposure and the processing step so the particular variant can be checked against its product data.

Check the actual water exposure, the surfaces and the design of the bonded joint. 3M describes resistance to moisture as a property of the VHB family; it does not establish that every component joint will be watertight. Suitability depends on the selected variant under the conditions of your application. Describe edges, transitions and possible loads before selecting a tape for a damp environment.
