3M™ 4611 VHB™ Tape is a 45 mil dark gray acrylic foam tape with a double-coated acrylic adhesive system engineered to replace mechanical fasteners such as screws, rivets, and welds. At 3/4 inch wide by 5 yards long, it delivers a structural bond on metals, plastics, glass, and painted or coated surfaces without adding visible hardware.

The tape carries a UL 746C listing for plastic component bonding and maintains reliable adhesion from -31°F to 300°F, making it appropriate for assemblies subject to heat cycling, outdoor weathering, UV exposure, moisture, and solvent contact. These characteristics make it a practical choice for electronics enclosures, automotive trim, architectural panels, and industrial equipment fabrication.

Construction features a 45 mil acrylic foam core protected by a red polyethylene liner prior to application. Sold as a single roll, this format suits low-volume bonding work, prototype builds, or initial evaluation before scaling to larger roll quantities. Ships via parcel.
