Industrial-grade double-sided VHB foam bonding tape with 45 mil thickness, permanent acrylic adhesive, and exceptional strength. Perfect alternative to rivets, welds, and screws for transportation, appliances, electronics, and construction applications.
3M™ VHB™ Tape 4941 is a premium double-sided bonding tape comprised of a multi-purpose acrylic adhesive with a conformable foam core backed on a 3 mil thick 54# densified kraft paper liner. This industrial-grade tape delivers a total thickness of 45 mil (1.1 mm) when applied, providing an excellent balance of strength, conformability, and adhesion to high and medium surface energy materials. The tape serves as a smooth, seamless alternative to traditional mechanical fasteners such as rivets, welds, and screws, as well as liquid adhesives. With immediate handling strength and no need for fixtures or cure time, this tape revolutionizes assembly and bonding processes across multiple industries.
The 3M™ VHB™ Tape 4941 features exceptional durability and performance characteristics that make it suitable for both indoor and outdoor applications. It delivers excellent shear strength, conformability, and surface adhesion thanks to its acrylic foam core and multi-purpose adhesive formulation. The tape offers outstanding outdoor durability, resisting both high and low temperatures as well as moisture, making it suitable for extreme environments from Dubai's heat to Canada's cold. It adheres effectively to a variety of High Surface Energy (HSE) and Medium Surface Energy (MSE) substrates including aluminum, stainless steel, galvanized steel, acrylic, polycarbonate, ABS, composites, and painted or sealed wood and concrete.
This versatile bonding solution is commonly used across transportation, appliance, electronics, construction, sign and display, and general industrial markets. The tape is UL GREENGUARD™ and UL GREENGUARD™ Gold Certified, helping contribute to LEED® credits. Each case contains 7 rolls of 36 yards in length and 1.099 inches in width, making it convenient for bulk purchasing and inventory management. The 24-month shelf life ensures long-term storage capability, while the conformable foam core allows for the use of thinner, lighter-weight, and dissimilar materials when compared to traditional fastening methods.
