3M 8979N Nuclear Grade Duct Tape 2 in x 60 yd Olive

This tape is a polyethylene coated cloth duct tape with a rubber adhesive, built for assembly, manufacturing, metalworking and warehouse tasks. It suits indoor and outdoor use across a 40 to 200 degrees Fahrenheit performance range. The olive colour and 11.5 mil thickness identify it for nuclear grade applications. Buyers needing a thinner tape or a different adhesive chemistry should look elsewhere.

Upgrades from standard duct tapes

Standard cloth duct tapes often use lower adhesion values and narrower temperature ranges. This product delivers 57 oz/in adhesion to steel and a continuous 60 yard roll for longer runs. The jump is worth it when the job demands consistent holding power at 200 degrees Fahrenheit or reliable bonding down to 40 degrees Fahrenheit. It does not replace specialised high-temperature foil tapes or low-residue masking tapes.

Installation notes

The tape unwinds from a continuous roll and applies by hand pressure to clean, dry surfaces. Common issues include reduced adhesion on oily, dusty or wet substrates and edge lifting if the tape is stretched during application. The rubber adhesive bonds quickly, so repositioning is limited once contact is made. No tools or surface primers are required for typical metal, plastic or painted surfaces.
