3M 4941 VHB Tape

3M 4941 VHB Tape

Description and Features

Product Description 3M VHB Tape 4941 utilizes multi-purpose acrylic adhesive on both sides of a conformable adhesive foam core. The adhesive provides excellent adhesion to a broad range of high and medium surface energy substrates including metals, glass, and a wide variety of plastics, as well as plasticized vinyl. The conformable adhesive foam core provides good contact, even with mismatched substrates. The combination of foam strength, conformability, and adhesion makes this family one of the most capable all-around 3M VHB™ tapes.
