3M 3939 Heavy Duty Duct Tape, Silver, .94 in x 60 yd x 9.0 mil – Professional Grade Water-Resistant Duct Tape for Sealing, Holding, Bundling and Reinforcing, Case of 36

Product Description Constructed of water-resistant polyethylene film laminated to cloth with a rubber adhesive, 3M Heavy Duty Duct Tape 3939 resists curling and tears off the roll cleanly for easy application in general indoor MRO/construction environments. The rubber adhesive sticks instantly and provides a tight moisture-resistant seal in many containment situations, while low tack roll edges stay cleaner. Designed for heavy-duty use, this conformable tape allows for a wide range of permanent and temporary solutions, including patching, bundling, reinforcing, tabbing, taping/splicing insulation, capping pipe, securing conduit ends, marking, labeling, temporary repairs and more. Can be used at temperatures as high as 200F for up to 30 minutes. From the Manufacturer 3M Heavy Duty Duct Tape 3939 is constructed of a water-resistant polyethylene laminated to cloth reinforcement and backed by an aggressive natural-rubber adhesive, making the tape 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 is also used in the convention industry for holding and seaming carpet padding, taping down cords and hinging poster-board panels.3M 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.
