3M Adhesive Tape 4991F Gray

The 3M™ VHB™ 4991 Adhesive Tape in gray impresses with its 2.3 mm thick, highly flexible structure made of closed-cell acrylate adhesive. Developed for permanently strong bonds, it is ideal for indoor and outdoor applications—especially where materials with medium to high surface energy need to be reliably bonded.

Thanks to its pressure-sensitive adhesive, the tape offers immediate adhesion and enables fast, clean work—without drilling, welding, or screwing. The virtually invisible bond line keeps designs clear and undisturbed. In addition to high shock and vibration absorption, the tape also provides a reliable seal against moisture and water.

The tape is ideal for replacing traditional joining methods such as rivets or liquid adhesives and works perfectly on painted, metallic, smooth, or textured surfaces—even with challenging material combinations or thin, lightweight materials.
