Very High Bond - Series 4900
These products are sold either by the Single Roll or can be ordered By the Foot or By the Yard.
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, conform-ability, high tensile strength, high shear and peel adhesion, resistance to plasticize migration, and UL746C recognition. All 3M™ VHB™ Tapes have excellent durability and excellent solvent and moisture resistance.

APPROXIMATE TIME TO ACHIEVE ULTIMATE BOND STRENGTH:
- 50% after 20 minutes
- 90% after 24 hours
- 100% after 72 hours
Bond strength may be achieved more quickly and in some cases, may be increased by exposing the bond to elevated temperatures (e.g. 150°F (66°C) for 1 hour).
USE THE RIGHT THICKNESS OF TAPE
The necessary thickness of tape depends on the rigidity of the substrates and their flatness or irregularity. While the 3M™ VHB™ Tapes will conform to a certain amount of irregularity, they will not flow to fill gaps between materials.
- For bonding rigid materials with normal flatness, consider use of tapes with thickness of 45 mils (1.1mm) or greater.
- As the substrate flexibility increases thinner tapes can be considered.
- Thinner tapes can be used to bond small rigid parts.
- Large parts where a higher degree of expansion and contraction is expected might need thicker tapes.
