3M 3M 389 Duct Tape, 50 m x 100mm, Black

This duct tape is a multi-purpose adhesive tape designed for industrial and workshop environments. It provides Durable surface protection and temporary bonding for mechanical, electrical and electronics tasks, with a polyethylene backing and a synthetic rubber adhesive for secure adherence across varied substrates.

• Synthetic rubber adhesive for strong initial tack and holding power
• Polyethylene backing offering resistance to abrasion and moisture
• 0.26mm thickness delivering stable handling and tear control
• Wide 100mm roll for efficient coverage of large joints
• 50m length reducing roll changes during extended tasks
• Black finish providing Visual contrast for masking and identification

• Suitable for temporary sealing of ducting and cable runs
• Ideal for repairing insulation on housings and conduits
• Used with panel assemblies for surface protection during fabrication
• Can be used for bundling harnesses and cable management
• Used for marking or blackout on enclosures and test rigs

The backing material limits moisture ingress and the adhesive maintains a bond on many surfaces, making it useful where occasional damp contact occurs.

The tape’s backing and thickness allow controlled tearing by hand along a straight line for most workshop uses while providing sufficient rigidity for neat application.

The adhesive adheres well to metal and plastics commonly found in enclosures, enabling temporary sealing and surface protection during assembly and maintenance.

The dark finish is useful for blackout and contrast purposes
