3M 389 Duct Tape, 50 m x 50mm, Yellow

This duct tape is a heavy-duty adhesive tape intended for sealing and repair tasks across industrial settings. It is designed to provide Durable adhesion and surface protection where a resilient, visible tape is required, particularly in automation, electrical, electronic and mechanical environments.

• Synthetic rubber adhesive delivers high initial tack and adhesion
• Polyethylene backing provides water-resistant surface protection
• 0.26mm thickness offers robust tear resistance and handling
• 50mm width supports broad-area coverage per wrap
• 50 m roll length reduces changeovers on site
• Yellow colour enhances visibility for safety and identification

• Suitable for temporary cable bundling in control panels
• Ideal for patching ducts and conduit joints on site
• Used for colour-coding and safety marking in workshops
• Can be used for surface protection during assembly processes
• Used for sealing joints on enclosures where moisture resistance helps

The synthetic rubber adhesive provides strong initial grab on common materials such as metals, plastics and painted surfaces, enabling quick bonding in assembly and maintenance tasks.

The polyethylene backing balances flexibility and tear resistance so the tape conforms to irregular shapes yet resists accidental ripping during laydown and trimming.

The backing material offers water-resistant properties that help maintain adhesion and barrier performance in damp or splash-prone areas.

The 50 m roll length reduces the frequency of roll changes, minimising downtime for repeated sealing or repair operations in production or maintenance routines.
