Duct Tape 3M 7100211838

3M 7100211838 duct tape is a versatile adhesive tape designed for general repairs and sealing tasks both indoors and outdoors. The tape is black, 12 mm wide, 33 m long and 1.6 mm thick, providing a balance of flexibility and strength for temporary fixes, bundling and light-duty sealing. Its adhesive formulation adheres to a range of common substrates including ceramics, metal, polycarbonate, polypropylene and wood, making it suitable for use on different surfaces in home, workshop and industrial settings.

Advantages

The tape combines a resilient backing with a pressure-sensitive adhesive to deliver reliable tack and holding power on multiple materials. Its 1.6 mm thickness adds durability for short-term protection and load distribution, while the 33 m length gives extended coverage for repeated tasks. The narrow 12 mm width enables precise application in confined areas or for detail work. Resistant to casual abrasion and suitable for both interior and exterior environments, this duct tape offers consistent performance for a variety of repair and sealing needs.

Suitable for

• Temporary repairs and patching of surfaces
• Sealing cable runs and bundling wires
• Mounting or holding lightweight components in place
• General purpose masking and surface protection in workshops
• Quick fixes on metal, wood, plastics and ceramic parts

Key specifications

• Length: 33 m
• Width: 12 mm
• Thickness: 1.6 mm
• Suitable substrates: ceramics, metal, polycarbonate, polypropylene, wood
• Usage environment: indoor and outdoor

How to use

Ensure surfaces are dry, clean and free of dust, oil or loose particles before applying the tape. Measure and cut the required length, then press the tape firmly onto the surface to obtain full contact and adhesion. For irregular or curved surfaces, apply with steady pressure and smooth from the center outwards to avoid air pockets. Remove by peeling slowly at a low angle; if adhesive residue remains, remove with a suitable solvent compatible with the substrate.

Usage recommendations

For best results, store the tape in a cool, dry place away from direct sunlight and extreme temperatures. Use the 12 mm width for narrow applications and detailed repairs; choose a wider tape for larger sealing or heavier-duty tasks. When used outdoors for extended periods, periodically inspect the tape for wear or loss of adhesion.
