4991

3M™ VHB™ Tape 4991 is a 90 mil thick conformable double sided foam tape. This tape features a versitile multi-purpose acrylic adhesive that is suitable for bonding onto high and medium surface energy materials while providing the added benefit of plasticizer migration resistance in vinyl substrates. Constructed with conformable foam, this tape achieves excellent bonding even when substrates are irregular or mismatched.

  • Fast and easy-to-use permanent bonding method provides high strength and long-term durability
  • Can replace mechanical fasteners (rivets, welds, screws) or liquid adhesives
  • Offers a good balance of strength and conformability
