3M 389 Duct Tape, 50 m x 75mm, Black, Black Finish

This duct tape is a robust, general-purpose sealing and repair tape designed for industrial and workshop use. It combines a polyethylene backing with an aggressive synthetic rubber adhesive to form a resilient black tape suited to demanding site and production-floor environments.

• Polyethylene backing provides moisture resistance and surface conformity
• Synthetic rubber adhesive ensures high initial tack for quick bonding
• 0.26mm overall thickness offers mechanical strength and puncture resistance
• 75mm width enables broad coverage for visible seams and joins
• 50m roll length reduces changeovers on repeated jobs
• Black finish conceals repairs and reduces Visual glare

• Suitable for temporary cable bundling and protective wrapping
• Ideal for sealing ducts and ventilation joints in maintenance work
• Used for patching enclosures and protective covers on machinery
• Can be used for surface repair on industrial packaging and crates
• Used for masking and light-duty holding during panel assembly

The flexible polyethylene backing conforms to irregular profiles while the synthetic rubber adhesive maintains contact, improving adhesion on curved or textured metal.

The backing resists water ingress and the adhesive retains tack in damp conditions, making it suitable for short-term exterior or workshop exposure.

Its 0.26mm thickness gives enhanced tear and abrasion resistance compared with thinner films, so it performs acceptably in moderate wear applications.

Store in a cool, dry location away from direct sunlight and extreme heat to prevent adhesive softening and backing deformation.
