Premium slate blue duct tape for industrial applications with UV and weather resistance up to one year, clean removal capability, and MIL-STD compliance for nuclear, maritime, and construction use.
The 3M™ Performance Plus Duct Tape 8979N is a highly specialized, premium-grade duct tape engineered for demanding industrial applications in nuclear power plants, shipbuilding, and steel fabrication industries. This industrial-strength tape features a distinctive slate blue color with a fabric-reinforced polyethylene film backing combined with a thick rubber adhesive that provides exceptional bonding strength. 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 requiring long-lasting performance.
Designed for high-strength bundling, holding, masking, and temporary repairs, this Performance Plus formulation offers superior adhesion to steel at 48 oz/in with a tensile strength of 36 lbs (63 N/cm). The tape's curl-resistant and moisture-resistant backing ensures easy handling and conformability to irregular and curved surfaces. It removes cleanly from most opaque surfaces after up to six months of UV exposure and weather, leaving minimal adhesive residue. With a total thickness of 12.1 mil (0.3 mm), this tape delivers the durability and reliability required for critical industrial operations.
Complying with MIL-STD-2041D(SH), Notice 2 for leachable halides and sulfur, the 3M Performance Plus Duct Tape 8979N is hand-tearable, writable, and suitable for use in automotive, construction, general industrial, MRO, marine, military, and government applications. Each case contains 12 rolls of 54.8 meters (59.93 yards) length, providing comprehensive coverage for large-scale projects. The tape operates reliably within a temperature range of 4°C to 93°C (40°F to 200°F) and maintains a 24-month shelf life for convenient inventory management.
