3M 3939 Silver Conduit Tape 1.88"

Description

Composed of a polyethylene film laminated to a canvas backing and a rubber adhesive, this durable tape resists curling and peels cleanly from the roll for easy application in MRE or construction applications. Furthermore, the 3MMC 3939 duct tape features a unique construction that allows for both permanent and temporary applications. It then removes with little to no adhesive residue.

Originally designed for heating, ventilation, and air conditioning (HVAC) applications, this tape is now used in a variety of maintenance, repair, and construction environments. It has been tested to ASTM UL723 and E84 standards. Its unique design also makes it an excellent choice for general indoor MRE/construction applications. The tape can withstand temperatures up to 93.3°C (200°F) for up to 30 minutes. The 3MMC 3939 High Performance Duct Tape features a classic silver backing. This heavy-duty, cloth-reinforced tape peels off the roll and adheres instantly, providing a wide range of practical solutions.
