Duct Tape 3M 14365050

The 3M 14365050 duct tape is a silver aluminum-colored sealing and protective tape suitable for indoor and outdoor use. With a length of 50 m and a width of 50 mm, this duct tape provides continuous coverage for repairs, sealing joints and ducts, temporary fixes, and surface protection. Constructed with a 0.075 mm thickness and formulated to withstand temperatures from -25 °C to 75 °C, the tape balances conformability and durability while offering a break elongation of 3.1% for reliable performance under tension.

Advantages

This duct tape combines weather resistance and adhesion suitable for general-purpose sealing and protective tasks. The silver aluminum finish reflects light and heat to some extent and helps create a visible, durable protective layer. Its specified temperature range and moderate thickness make it useful for both short-term and longer-lasting applications where flexibility and surface conformity are required. The tape’s dimensions provide a practical balance between coverage length and handling convenience.

Подходит для

• Temporary repairs to metal, plastic and composite surfaces
• Surface protection during painting or refurbishment
• Bundling and securing cables or hoses for short-term use
• Weatherproofing and insulating minor leaks and seams

Key specifications

• Color: silver aluminum
• Length: 50 m
• Width: 50 mm
• Thickness: 0.075 mm
• Break elongation: 3.1%
• Operating temperature range: -25 °C to 75 °C

How to use

Ensure the surface is clean, dry, and free of loose particles, oils or dust before applying the tape. Measure and cut the required length, then press the tape firmly onto the surface, smoothing out wrinkles and air pockets for best adhesion. For seams or joints, overlap edges as needed to achieve a continuous seal. For outdoor applications, press edges down firmly and check adhesion after initial exposure to weather. Remove by peeling back slowly; some adhesive residue may remain on porous surfaces.

Usage recommendations

Use on clean, smooth surfaces for optimal adhesion. Not intended as a permanent structural repair for load-bearing applications; for long-term exterior exposure in extreme conditions consider periodic inspection and replacement. Store in a cool, dry place away from direct sunlight to preserve adhesive performance.
