Premium double-sided foam bonding tape with multi-purpose acrylic adhesive, 45 mil thickness, designed as alternative to rivets, welds and screws for permanent industrial bonding applications.
3M™ VHB™ Tape 4941 is a premium double-sided bonding tape featuring a multi-purpose acrylic adhesive with a conformable foam core backed on densified kraft paper liner. This industrial-grade tape delivers a total thickness of 45 mil (1.1 mm) and provides an excellent balance of strength, conformability, and adhesion to high and medium surface energy materials. The tape is designed as a smooth, seamless alternative to traditional mechanical fasteners such as rivets, welds, and screws, or liquid adhesives, making it ideal for permanent bonding applications across multiple industries.
The 3M™ VHB™ Tape 4941 combines viscoelastic properties with durable acrylic chemistry to deliver extraordinary bonding power while maintaining excellent shear strength and surface adhesion. This tape adheres reliably to a broad range of substrates including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. With immediate handling strength and no need for fixtures or cure time, this tape accelerates assembly processes while enhancing finished product appearance by eliminating visible fasteners.
Offering exceptional outdoor durability and performance, the 3M™ VHB™ Tape 4941 resists both high and low temperatures as well as moisture, making it suitable for indoor and outdoor applications. The tape is UL GREENGUARD™ and UL GREENGUARD™ Gold Certified, contributing to LEED® credits for sustainable building projects. Commonly used in transportation, appliance, electronics, construction, sign and display, and general industrial applications, this versatile tape enables designers to use thinner, lighter-weight, and dissimilar materials compared to traditional fastening methods.
