Duct Tape 3M 7100211839

The 3M 7100211839 duct tape is a durable general-purpose tape designed for indoor and outdoor applications. It combines a resilient backing with a strong acrylic adhesive formulated to provide reliable holding power. The tape is supplied in a 33 m roll with a narrow 19 mm width and a 1.6 mm overall thickness. It is suitable for temporary joins, repairs, and fastening tasks where a black, high-strength tape is required and performs within a specified temperature range.

Advantages

The tape delivers a high tensile strength of 620 N/mm² and consistent adhesion on a variety of surfaces. Its acrylic-based adhesive offers good initial tack and long-term holding performance while resisting environmental factors encountered in both indoor and outdoor conditions. The product’s thickness and backing construction contribute to tear resistance and conformability for wrapping, bundling, and reinforcing tasks.

Suitable for

• Temporary joins and repairs of cables, hoses and ducts
• Fastening and bundling components in workshops and construction sites
• Sealing and securing lightweight panels and insulation
• General-purpose masking and surface protection in maintenance tasks

Key specifications

• Adhesive type: acrylic
• Tensile strength: 620 N/mm²
• Length: 33 m
• Width: 19 mm
• Thickness: 1.6 mm
• Color: black
• Operating temperature range: effective use between 120 °C and 150 °C
• Suitable for indoor and outdoor use

How to use

Ensure surfaces are clean, dry and free of dust, oil or loose particles before applying the tape. Cut or tear the required length, press the tape firmly onto the substrate and smooth it with hand pressure to improve initial adhesion. For bundling or securing, wrap with moderate tension and overlap the ends to prevent peel-back. When used outdoors, check periodically for wear or environmental degradation and replace as needed.

Usage recommendations

For optimal performance, apply the tape within its effective temperature range and avoid prolonged exposure to temperatures or chemicals outside those limits. Store rolls in a cool, dry place away from direct sunlight to maintain adhesive properties. For critical load-bearing applications, verify compatibility with the substrate and consider mechanical fastening as a secondary measure.
