Description
3M(TM) Heavy Duty Duct Tape
3939 has the tensile strength
and adhesion for splicing,
masking, patching, seaming,
hanging poly sheeting,
sealing PVC pipes, covering
trip hazards and a host of
other industrial applications.
3M(TM) Heavy Duty Duct Tape
3939 is constructed of a
water-resistant polyethylene
laminated to cloth
reinforcement and backed by
an aggressive natural-rubber
adhesive, the tape is
high-tack and conformable.
Our tape tears easily and
cleanly—horizontally or
vertically—without slivering.
Industrial applications
include hanging polyethylene
drapes for containment
activities, masking, and
sandblast overspray
protection. It is also used
in the convention industry
for holding and seaming
carpet padding, taping down
cords, and hinging
poster-board panels.
3M(TM) Heavy Duty Duct Tape
3939 can be used in
temperatures up to 200
degrees F. It has been burn
tested according to the
methods UL 723, ASTM E-84,
NFPA 255, UBC 8-1. Results
were Flame Spread Index 0,
Smoke Developed Index 30.
Duct tape (sometimes
mistakenly referred to as
“duck tape”) is a toolbox
mainstay, used in
maintenance, repair and
construction operations. The
term “duct tape” comes from
the silver tape’s original
use in heating, ventilation
and air conditioning (HVAC)
applications, including duct
sealing. Today it performs
wherever patching, bundling,
reinforcing, tabbing,
splicing insulation, capping
pipe and conduit ends,
labeling, temporary repair,
hanging polyethylene drapes,
or protecting against light
sandblast overspray is
needed. Duct tape is used in
residential, industrial and
commercial environments and
by members of construction,
electrical, industrial,
marine, and military,
abatement, trucking, and
automotive markets.
