3M Adhesive Tape 4646F

The 3M™ VHB™ Adhesive Tape 4646 is a 0.6 mm thick, high-performance double-sided adhesive tape in dark gray, designed for durable, high-strength bonds on materials with high surface energy such as aluminum, stainless steel, or galvanized steel. The universal acrylic pressure-sensitive adhesive offers immediate serviceability, long-term durability, and excellent resistance to high temperatures, chemicals, and UV radiation.

The tape effectively replaces mechanical fasteners such as screws, rivets, or welds, thereby eliminating the need for drilling, grinding, finishing, and cleaning. The viscoelastic properties of the adhesive enable high dynamic load absorption, thereby reducing vibrations and shocks. In addition, 3M™ VHB™ 4646 provides a permanent seal against water, moisture, and dirt.

Thanks to its high temperature resistance, the tape is ideal for bonding metal parts prior to high-temperature painting—a significant advantage in industrial applications. It is part of the 3M™ VHB™ 4611 product family and stands for reliability, strength, and precision in assembly, fastening, and sealing processes in the metal, electronics, construction, and appliance industries.

3M™ VHB™ Tape 4646 provides a virtually invisible bond for a clean, professional design while improving the efficiency of your manufacturing processes.
