3M 3939 Heavy Duty Duct Tape Silver 48mm x 54.8m

Industrial-grade duct tape for splicing, masking, patching, sealing, and seaming

3M 3939 Heavy Duty Duct Tape 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. This 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's also used in the convention industry for holding and seaming carpet padding, taping down cords, and hinging poster-board panels.

3M 3939 Heavy Duty Duct Tape can be used in temperatures up to 93°C. 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.
