VHB ? Tapes
Technical Data
June, 2011
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.
Note: All 3M? VHB? Tapes should be thoroughly evaluated by the end user under actual use conditions with intended
substrates to determine whether a specific tape is fit for a particular purpose and suitable for user ’s method of application,
especially if expected use involves extreme environmental conditions or high dead load stress.

3M? VHB? Tapes Adhesive Types:
Multi-Purpose Acrylic: This adhesive bonds to a wide range of materials including metals, glass, and high and medium surface
energy plastics and paints. This unique adhesive also has the ability to resist migration of plasticizers in vinyl substrates.
Modified Acrylic: This adhesive bonds to medium low surface energy paints and plastics, including many powder coated
paints in addition to the substrates listed with the multi-purpose acrylic adhesive (except plasticized vinyl).
General Purpose Acrylic: This adhesive bonds to most higher surface energy substrates including metal, glass and high
surface energy plastics.
Low T emperature Appliable Acrylic: This adhesive can make bonds down to 32°F (0°C), compared to 50°F (10°C) for most
acrylic adhesives. This adhesive system bonds to most high surface energy substrates including metal, glass and high surface
energy plastics.
Low Surface Energy: This high performance synthetic adhesive bonds to many lower surface energy substrates, including
many plastics and power coated paints, plus smooth general purpose substrates.
3M? VHB? Tapes Foam Types:
Conformable: This foam provides high strength with the capability of conforming to the irregularities of rigid substrates,
even when there might be slight mismatch.
Very Conformable: This foam provides the highest level of conformability while maintaining high internal strength.
Firm: This foam provides the highest level of foam strength in the 3M? VHB? Tapes family.
Clear: Not technically a foam, this solid acrylic material provides excellent clarity.
