Premium slate blue duct tape with heavy-duty rubber adhesive, designed for industrial applications. Resists UV and weather for up to one year, removes cleanly within six months, and complies with military standards.
3M™ Performance Plus Duct Tape 8979N is a highly specialized, premium-grade duct tape engineered for demanding industrial applications including nuclear power plants, shipbuilding, and steel fabrication. This slate blue colored tape features a fabric-reinforced polyethylene backing with a thick rubber adhesive that provides exceptional holding power and clean removal properties. The tape resists UV exposure, sunlight, and weather conditions for up to one year without deterioration, making it ideal for both indoor and outdoor applications. With dimensions of 48mm width and 54.8 meters length per roll, this tape delivers high tensile strength of 36 pounds and superior adhesion to steel at 48 oz/in, ensuring reliable performance in heavy-duty bundling, sealing, and protection tasks.
The Performance Plus formulation offers curl-resistant, moisture-resistant backing that conforms easily to irregular and curved surfaces while remaining hand-tearable and writable. This tape removes cleanly from most opaque surfaces after up to six months of UV exposure and outdoor weathering, leaving minimal adhesive residue. It complies with MIL-STD-2041D(SH), Notice 2 for leachable halides and sulfur, making it suitable for specialized industries requiring low leachable contaminants. The distinctive slate blue color provides easy identification and differentiation from standard silver duct tape in work environments.
Each case contains 24 rolls, with each roll featuring a 3-inch (76.2mm) core size. The tape operates effectively in temperature ranges from 40°F to 200°F (4°C to 93°C) and maintains a 24-month shelf life. With a 12.1 mil thickness and premium tape grade classification, this product is designed exclusively for industrial and occupational use, delivering reliable performance in automotive, construction, general industrial, MRO, marine, military, and specialty vehicle applications.
