3M Adhesive Tape 4646F

The 3M™ VHB™ Tape 4646 is a 0.6 mm thick, double-sided high-performance adhesive tape in dark gray with a universal acrylic pressure-sensitive adhesive that delivers reliable performance even at high temperatures. It enables fast, clean, and durable bonding and effortlessly replaces conventional mechanical fasteners such as screws, rivets, or welds—without any drilling, grinding, or post-processing.

Thanks to its viscoelastic properties, the tape absorbs vibrations and shocks while providing a permanent seal against water, moisture, and dirt. Due to its excellent temperature resistance, it is ideal for bonding metal parts prior to high-temperature painting, such as in metalworking or industrial coating processes.

As part of the 3M™ VHB™ 4611 product family, the 4646 is specifically designed for materials with high surface energy such as aluminum, stainless steel, or galvanized steel. It enables virtually invisible bonds, which promotes a clean, modern design. Additionally, it remains resistant to chemicals, UV radiation, and extreme temperature fluctuations, ensuring long-lasting performance both indoors and outdoors.

With its proven 3M™ technology, the VHB™ 4646 adhesive tape offers a reliable, fast, and efficient solution for demanding applications in industry, electronics, architecture, and automotive manufacturing.
