- Strong, water-resistant backing resists wear and light abrasion
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. The 3M™ Duct Tape 3939 has a unique construction that allows for permanent and temporary applications. It is removable with little or no adhesive residue.
Originally developed for heating, ventilating and air conditioning (HVAC) applications, duct tape is used today in a variety of maintenance, repair and construction settings. The 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 applications in MRO/construction. The tape can be used in temperatures as high as 200°F (93.3°C) for up to 30 minutes. The 3M™ Heavy Duty Duct Tape 3939 comes with a classic, silver-coloured backing. This sturdy, cloth-reinforced tape can be torn from the roll and sticks instantly, providing a wide range of convenient solutions.
