3M™ VHB™ tapes 

Very High Bond Tapes aid device assembly

The 3M™ family of VHB™Tapes are made of CLOSED CELL acrylic foam, and offer flexibility in applications with dynamic forces in exterior environments. The VHB™Tapes  acrylic foam chemistry provides outstanding durability for OEM applications.  While many applications can be satisfied with 3M 4941, 3M 4950, and 3M 5952, a review for your application will insure the correct recommendation.

NEW - 3M™ VHB™ Tapes are now available for Thin Foam Applications.  Need a thinner bond line? Thinner tapes go where thicker tapes can't, including LCD, lens, touch panel bonding, logo attachment, point of purchase and display construction.  Thinner VHB™ tapes dissapate stress and resist chemicals and moisutre over long periods in outdoor and harsh conditions.  Download spec sheets for 3M™ VHB™ Thin Foam tapes in the 3M™ VHB™ 5900 family, 3M™ VHB™4914, or the 3M™ VHB™86400 family.

  • Easily die-cut - precisely fit shapes, and aid in assembly.
  • Strength - Displace traditional fasteners like rivets, liquid adhesives, spot welds and other fasteners.
  • Clean appearance - No unsightly rivets or spot welds.
  • Seals - tape runs the length of the bond line, and seal. Excellent water and humidity resistance.
  • Vibration resistant - acrylic foam distributes stress over entire area, damp vibration.
  • Durability - in continuous use for applications for more than 25 years.
  • Seperates metals to reduce potential galvanic corrosion.

        VHB™ Thin Foam Tapes Technical Facts:

  • Good for most normal outdoor applications from -40ºF- 200ºF
  • Additional products available for higher temperature applications
  • Bond build is enhanced by higher temperatures. Min. tack is 50ºF or more
  • Foam softens in water, and maintains a strong bond. Submersion applications may require additional testing and validation.
  • Solvents swell adhesives, not dissolve. Splash and incidental contact should be fine, solvent submersion is NOT recommended.
