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 provide these tapes with their unique characteristics. The acrylic chemistry provides outstanding durability performance.
