| Very High Bond - Series 4600, 4900, 5900 |
3M™ 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™ 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 use 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™ Tapes have excellent durability and excellent solvent and moisture resistance.
These are custom ordered, full case only. Depending on the width chosen, a case will contain 2-18 rolls of product. Orders usually ship between 5 and 8 business days depending on stock at 3M.

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 TAPE FOR THE SURFACES INVOLVED
Adhesion is the molecular attraction between unlike materials, similar to magnetic force. Strength of
attraction is generally determined by the surface energy of the material. The higher the surface
energy, the greater the attraction. The lower the surface energy, the weaker the attractive forces.
On high surface energy surfaces a tape or adhesive can flow or "wet out" to assure a stronger bond.
These surfaces include aluminum, steel or glass. On low surface energy surfaces most adhesives and
tapes will resist flowing onto the surface, leaving poor surface contact and low adhesion strength.
Traditionally substrates have been categorized as having high surface energy or low surface energy as
it relates to bonding with adhesives. With the increasing number of substrates and with new adhesives
it is common to identify substrates as having medium surface energy or even medium high or medium
low surface energy.
Because the surface energy defines a level at which the adhesive can wet and bond to the surface,
generally an adhesive type can bond to surfaces with a particular surface energy level and higher.
Following are guidelines for matching 3M™ VHB™ Tapes adhesive types with typical substrates.
