8979 Slate Blue Duct Tape

3M 8979 is a clean removal duct tape built for indoor and outdoor repair tasks. The polyethylene coated cloth backing with rubber adhesive delivers a continuous roll suited to general construction and HVAC work. It performs across a temperature range of 40 to 200 degrees Fahrenheit.

Polyethylene coated cloth with rubber adhesive

The tape measures 2 inches wide by 25 yards long with a thickness of 11.5 mil and adhesion to steel rated at 57 oz/in. The slate blue colour allows quick visual identification on site. Rubber adhesive enables clean removal after temporary holding or sealing jobs without leaving residue on ductwork or surfaces.

Replaces standard silver duct tape

This product upgrades from basic duct tapes when clean removal and temperature resistance are required. The jump is worth it for installers who need reliable holding power up to 200 degrees Fahrenheit and want to avoid adhesive residue on finished surfaces after the job is done.

Questions about this item

What temperature range does the 8979 tape handle in service?

The tape is rated for continuous use from 40 °F up to 200 °F.

What surface width and roll length do I need to plan for the 2 in wide 8979 roll?

Each roll is 2 inches wide and 25 yards long, giving 50 feet of coverage per roll.

How do I apply the 8979 clean-removal tape so it releases cleanly later?

Press the polyethylene-coated cloth firmly onto a clean, dry surface; avoid stretching the tape during application, as over-stretching is the step most often missed and causes adhesive residue on removal.
