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

This duct tape provides a resilient sealing and repair solution for industrial environments. Designed for general-purpose adhesion and surface protection, it combines a flexible polyethylene backing with a pressure-sensitive rubber adhesive to perform on a variety of substrates common in electrical, mechanical and automation settings.

• Polyethylene backing offers moisture resistance and surface conformity
• Synthetic rubber adhesive delivers immediate strong tack for quick repairs
• Thickness 0.26mm resists puncture and abrasion during handling
• Width 50mm supports precise application on ducts and cable runs
• Length 50 m reduces frequent roll changes on site

• Suitable for sealing HVAC duct joints and seams
• Ideal for temporary insulation of wiring harnesses
• Used for holding protective films during assembly work
• Can be used for patch repairs on conduit and cable trays
• Used with HVAC fittings where moisture resistance is required

The flexible backing conforms to irregular profiles, maintaining contact so the adhesive can form an effective bond across seams and joints.

The synthetic rubber formulation provides Rapid tack, enabling short-term holds and provisional fixes while permanent repairs are prepared.

The backing material reduces water ingress at the bond line, helping the adhesive maintain adhesion in damp or condensating environments.

Apply with firm pressure and smooth from centre outwards to eliminate entrapped Air and ensure uniform contact across the surface.
