Industrial-grade double-sided foam tape with permanent bonding, 90 mil thickness, gray color, 3/4 in x 36 yd roll. Provides immediate handling strength without cure time, excellent temperature and moisture resistance, and adheres to metals, plastics, and composites.
3M™ VHB™ Tape 4991 is a premium double-sided foam tape comprised of a multi-purpose acrylic adhesive with a conformable foam core backed on a 5 mil red printed polyethylene film liner, delivering a total thickness of 90 mil (2.3 mm) when applied. This high-performance bonding tape provides an excellent balance of strength, conformability, and adhesion to high and medium surface energy materials, making it a smooth, seamless alternative to rivets, welds, and screws. The tape's unique acrylic chemistry with viscoelastic properties delivers extraordinary bonding power while maintaining flexibility and conformability to irregular surfaces.
Designed for industrial and occupational applications, 3M™ VHB™ Tape 4991 offers exceptional durability and performance across extreme environmental conditions. The closed-cell acrylic foam core ensures reliable bonding even in challenging temperatures ranging from -40°C to 121°C, while providing excellent resistance to moisture, UV exposure, and chemical solvents. This versatile tape adheres to a broad range of substrates including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete surfaces.
With immediate handling strength and no need for fixture or cure time, 3M™ VHB™ Tape 4991 significantly streamlines assembly and manufacturing processes across multiple industries. The tape's superior shear strength and surface adhesion make it ideal for applications ranging from transportation and appliance manufacturing to electronics, construction, signage, and general industrial use. Certified with UL GREENGUARD™ and UL GREENGUARD™ Gold certifications, this tape helps contribute to LEED® credits while delivering proven reliability and consistent bonding performance that manufacturers worldwide depend on.
