Q12. Will it hold underwater?
A. If the tape is applied to a dry surface and has bonded well, it will
hold underwater for a time because the backing is waterproof.
However, adhesive is exposed to water at the tape edge. Over
time, water will seep in at the edge and cause the tape to let
loose. Because the water has compromised the integrity of the
tape, you may also see adhesive transfer on removal.
Q13. What UL standards does it meet?
A. 3M
™
Performance Plus Duct Tape meets the requirements of
UL723 which rates the relative flame spread. For example, the
flame spread index of red oak flooring is set at 100 and cement
board is set at 0. To meet UL723 (also NFPA 255, ANSI 2.5,
UBC 8-1(42-1)), the flame spread index must be 25 or less and
smoke developed index must be 50 or less. 3M Performance Plus
Duct Tapes, 8979 and 8979N, have a Flame Spread Index of 5
and a Smoke Developed Index of 0 when tested according to
ASTM E84-01. 3M Performance Plus Duct Tape does not meet
UL181 A-P or UL181 B-FX.
Q17. What colors are available?
A. 3M
™
Performance Plus Duct Tape 8979 is available in slate
blue, olive, and black. 3M Performance Plus Duct Tape 8979N

Q14. Is it flame retardant?
A. Probably not. We have not added chemicals to make 3M
Performance Plus Duct Tape 8979 or 8979N flame retardant, and
have not tested for flame retardancy. If a customer has an interest,
please contact us with the specification that defines flame
retardancy for them.
Q15. Can you write on it?
A. Absolutely. Like most duct tapes, the backing will accept both
ballpoint pen and marker. Marker ink may smudge until it has
a few seconds to dry.
Q16. What is the shelf life?
A. 3M Performance Plus Duct Tapes 8979 and 8979N can be
used up to 12 months after the date of manufacture when stored
under normal conditions of 60º to 80ºF (16º to 27ºC) and 40 to
60% R.H. in the original carton. The month and year of
