Premium double-sided foam bonding tape with acrylic adhesive, 48 in x 36 yd, 45 mil thickness, ideal for industrial assembly, panel bonding, and sealing applications across multiple industries.
3M™ VHB™ Tape 4941 is a premium double-sided foam tape that combines an acrylic adhesive with a conformable foam core backed by densified kraft paper liner. With a total thickness of 45 mil (1.1 mm), this industrial-grade tape delivers exceptional bonding strength and versatility for a wide range of applications. The tape provides immediate handling strength without requiring fixtures or cure time, making it an ideal permanent bonding solution for modern manufacturing and assembly processes.
This specialized tape features a multi-purpose acrylic adhesive formulation that excels at bonding high and medium surface energy materials including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed surfaces. The closed-cell acrylic chemistry provides excellent shear strength, conformability, and surface adhesion while maintaining outstanding durability in extreme environments. 3M™ VHB™ Tape 4941 is specifically engineered as a superior alternative to mechanical fasteners such as rivets, welds, and screws, as well as liquid adhesives, offering cleaner aesthetics and faster assembly times.
The tape is certified by UL GREENGUARD™ and UL GREENGUARD™ Gold, contributing to LEED® credits for sustainable building practices. With a 24-month shelf life and rated for operation from extreme cold to extreme heat, this tape withstands temperatures ranging from -40°C to 149°C (-40°F to 300°F). Each roll measures 48 inches wide by 36 yards long, providing ample coverage for industrial applications across transportation, appliance, electronics, construction, signage, and general manufacturing sectors.
