3M® 3903 vinyl film duct tape is for coding pipes and conduit, identifying trip hazards, fine line paint masking, and much more. Constructed of polyethylene film laminated to cloth with a rubber adhesive, this economical tape resists curling and tears off the roll cleanly for easy application in MRO/construction. Extra Heavy Duty Duct Tape has a unique construction that allows for permanent and temporary indoor applications. It is removable with little or no adhesive residue up to three months after application. This industrial strength duct tape owes its strength and reliable performance to its abrasion resistant, water proof polyethylene film backing. Its dense cloth scrim and aggressive rubber adhesive combine with the backing to produce an effective tape that conforms, sticks where needed, seals, protects and meets dozens of other demanding applications.
