3M 3903 Red Duct Tape 50 yd

This 3M 3903 duct tape comes in a red vinyl-coated cloth backing with a rubber adhesive. The continuous roll measures 50 yards long by 1 inch wide and has a thickness of 6.5 mil. It is rated for a maximum performance temperature of 200 degrees F and provides adhesion to steel of 15.4 oz/in. The tape is designed for general purpose use in assembly, manufacturing, maintenance and repair tasks.

Suited for indoor repair and bundling jobs

The tape works well for indoor environments such as warehouses, safety marking and general maintenance where a durable cloth-backed tape is needed. It is not intended for buyers who require specialised electrical insulation ratings or outdoor weathering performance beyond the stated temperature limit. Users needing a different width, length or adhesive formulation should look at other options.

Holds under sustained heat up to 200 degrees F

Under continuous load the rubber adhesive maintains its bond up to the rated 200 degrees F maximum performance temperature. The vinyl-coated cloth backing resists tearing during prolonged stress, while the 6.5 mil thickness provides consistent shear resistance. Adhesion to steel remains stable at 15.4 oz/in throughout the operating range rather than dropping off after an initial burst.
