Premium double-sided foam tape for permanent industrial bonding with immediate handling strength, excellent temperature and moisture resistance, and versatile substrate adhesion. UL GREENGUARD certified alternative to rivets, welds, and screws.
3M™ VHB™ Tape 4941 is a premium double-sided foam tape engineered for permanent bonding applications across diverse industrial sectors. Composed of a multi-purpose acrylic adhesive with a conformable foam core backed by a 3 mil thick densified kraft paper liner, this tape delivers a total thickness of 45 mil (1.1 mm) when applied. The tape provides exceptional shear strength, conformability, and surface adhesion to both high and medium surface energy materials, making it an ideal seamless alternative to mechanical fasteners such as rivets, welds, and screws, as well as liquid adhesives.
This versatile bonding solution is specifically designed for applications requiring immediate handling strength without the need for fixture time or cure waiting periods. The acrylic foam core combined with multi-purpose adhesive technology ensures excellent outdoor durability and performance, resisting extreme temperatures from -40°C to 149°C (-40°F to 300°F) and maintaining moisture resistance. The tape adheres reliably to aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete surfaces.
The 4941 family represents over 40 years of 3M innovation in foam tape technology, first invented in 1980. It is UL GREENGUARD™ and UL GREENGUARD™ Gold Certified, contributing to LEED® credits and sustainable building practices. Commonly employed in transportation, appliance, electronics, construction, signage and display, and general industrial markets, this tape enables designers to utilize thinner, lighter-weight, and dissimilar materials compared to traditional fastening methods. With a 24-month shelf life and proven reliability in extreme environments from Dubai's heat to Canadian cold, 3M™ VHB™ Tape 4941 stands as a trusted, long-lasting bonding solution.
