Constructed of polyethylene film laminated to cloth with a rubber adhesive, this durable tape resists curling and tears off the roll cleanly for easy application in MRO/construction. Our 3M™ heavy duty duct tape 3939 has a unique construction that allows for permanent and temporary applications. It is removable with little or no adhesive residue up to 3 months after application. Originally developed for heating, ventilating and air conditioning (HVAC) applications, duct tape is used today in a variety of maintenance, repair and construction settings. Our 3M™ heavy duty duct tape 3939 was tested according to UL723, ASTM E84. Due to its unique design, it is an excellent choice for general indoor application in MRO/construction. The tape can be used at temperatures as high as 200 deg f for up to 30 min. 3M™ heavy duty duct tape 3939 comes with a classic, silver colored backing. Our sturdy cloth reinforced tape can be torn from the roll and sticks instantly, providing a wide range of convenient solutions. 3M™ family of rugged cloth and duct tapes adheres to most surfaces for applications ranging from bundling to moisture proofing, sealing to splicing, reinforcing to hanging poly drapes. Available in a variety of colors and strengths, they're known best for their hand tear ability, high tensile strength and conformability.
