Professional-grade double-sided foam tape with acrylic adhesive for permanent industrial bonding. Provides immediate handling strength, excellent shear strength, and superior conformability. Ideal alternative to rivets, welds, and screws. Bonds aluminum, steel, plastics, composites, and more. 9 rolls per case.
3M™ VHB™ Tape 4991 is a professional-grade double-sided foam tape designed for permanent bonding applications across industrial markets. Featuring a multi-purpose acrylic adhesive combined with a conformable foam core, this tape delivers exceptional strength, conformability, and surface adhesion. The tape is backed with a 5 mil red printed polyethylene film liner and provides a total thickness of 90 mil (2.3 mm) when applied. This innovative bonding solution offers immediate handling strength without requiring fixtures or cure time, making it an ideal alternative to mechanical fasteners such as rivets, welds, and screws, as well as liquid adhesives.
The 4991 tape is engineered to bond a broad range of substrates including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. Its excellent shear strength and viscoelastic properties ensure reliable performance in demanding applications. The tape excels in environments ranging from extreme heat to cold temperatures, resisting moisture and UV exposure while maintaining consistent bonding performance. With UL GREENGUARD™ and UL GREENGUARD™ Gold certification, this tape contributes to LEED® credits and meets stringent environmental standards.
Commonly used in transportation, appliance, electronics, construction, sign and display, and general industrial applications, the 3M VHB Tape 4991 enables designers to use thinner, lighter-weight, and dissimilar materials compared to traditional fastening methods. Each case contains 9 rolls, with each roll measuring 1 inch wide by 36 yards long, providing 324 linear yards of premium bonding tape per case. This tape represents 40+ years of proven reliability from 3M's Industrial Adhesives and Tapes Division, trusted by manufacturers worldwide for critical assembly, mounting, fastening, and sealing processes.
