3M™ VHB™ Tape 4950 replaces screws, rivets and studs to permanently adhere one substrate to another while spreading the stress load across the entire length of the joint. Once materials are joined with 3M VHB Tape, a virtually indestructible weld is created. 3M™ VHB™ tape combines the most conformable acrylic foam with modified acrylic adhesive.
Eliminate drilling, grinding, refinishing, screwing, welding and clean-up
Pressure sensitive adhesive bonds on contact with no drying time
Virtually invisible fastening helps keep surfaces smooth; no unsightly rivet heads or weld marks
Continuous bond distributes stress over entire length of the joined surfaces
Creates a permanent seal against water, moisture, salt and more
The result is an extraordinarily strong tape that adheres to the broadest range of substrates, including aluminum, stainless steel, galvanized steel, glass/epoxy, MSE plastics such as rigid PVC, acrylic, polycarbonate, ABS and polystyrene, most powder-coated paints, painted or sealed wood and concrete. VHB tape can be used both indoors and out in a variety of applications, including permanent sign and panel mounting, general industrial, maintenance and repair.
3M VHB Tapes in Industry
We introduced 3M VHB tapes in 1980 as the first of their kind. These unique tapes combine conformability and a strong permanent bond. The result is a family of extraordinarily strong tapes that adhere to a broad range of substrates, including glass, metal, MSE plastics such as rigid PVC, acrylic, polycarbonate, ABS and polystyrene, most powder-coated paints, painted or sealed wood and sealed concrete. 3M VHB Tape can be used both indoors and out in a variety of applications, including permanent sign and panel mounting, component attachment, and maintenance and repair.
3M™ VHB™ Tape is a proven alternative to screws, rivets, welds and other forms of mechanical fasteners. Skyscrapers, cell phones, electronic highway signs, refrigerators, marine electronics, architectural windows, recreational vehicles and trailers all rely on specialty bonding tape for one or more steps in the assembly, mounting, fastening and sealing process.
The Better Way to Bond
We make 3M™ VHB™ tape to fit into grooves, around corners and through curves while offering a durable bond in a way that mechanical fasteners can't. This innovation provides opportunities for quick, effective construction and the ability to design structures in new and different ways. The result is an extraordinarily strong tape that holds fast to a wide range of materials. Applications include bonding and sealing lenses over LED panels, bonding pre-painted metals, bonding and sealing plastic windows to pre-painted panel. When you use 3M VHB Tape, you can enhance 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. Our versatile line of tape can be used indoors or outdoors in a variety of applications, including window and door assembly, sign assembly, electronics, maintenance and dozens of other industrial applications.
