3M VHB Tape 4950
3M VHB Tape 4950
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

Product Description:
3M VHB Tapes provide the convenience and simplicity of a tape fastener and are ideal for use in many interior and exterior bonding
applications. In many situations, they can replace rivets, spot welds, liquid adhesives and other permanent fasteners.
These 3M VHB Tapes are made with acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing and stress
relaxing properties which provides these tapes with their unique characteristics. The acrylic chemistry provides outstanding durability
performance.
These tapes utilize a variety of specific foam, adhesive, color and release liner types to provide each product/family with specific features.
These features can include adhesion to specific or a broad range of materials, conformability, high tensile strength, high shear and peel
adhesion, resistance to plasticizer migration, and UL746C recognition. All 3M VHB Tapes have excellent
durability and excellent solvent and moisture resistance.
The tapes included in this data page have unique performance features that are not typically required in most common applications.
Please refer to 3M VHB Tapes technical data sheet for applications that do not require the special features incorporated in these
specialty tapes.
