VHB™ Tape Specialty Tapes

Technical Data

October 2014

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.
