Constructed of polyethylene film laminated to cloth with a synthetic rubber adhesive, this very thick and strong tape resists curling and tears off the roll cleanly even when used in the most demanding jobs. 3M™ super duty duct tape DT17 is designed to provide a maximum strength, long lasting solution for the ultimate applications. Originally developed for heating, ventilating and air conditioning (HVAC) applications, duct tape is used today in a variety of maintenance, repair and construction settings. Due to its unique design and price, 3M™ super duty duct tape DT17 is considered the strongest choice for the jobs where the thickest tape is necessary. It can be applied in temperatures as low as 40 deg F and used in temperatures as high as 130 deg f for up to 30 min. 3M™ super duty duct tape DT17 is available exclusively in black. Despite it being the thickest of 3M™ duct tapes, its polyethylene backing can be torn from the roll to stick instantly. While it bonds firmly to a number of substrates - including plastic, glass and sealed concrete - it is ideal for jobs involving the repairing, seaming and protection of metal parts and surfaces. 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 thickness and strengths, these tapes are known best for their hand tear ability, high tensile strength and conformability.
