• Less prone to leave adhesive residue on the surface than conventional cloth duct
tapes. Allows for minimal clean-up.
• Even after outdoor exposure, black will hold well for up to six months as is less
prone to leave adhesive residue compared to conventional duct tapes. Red, green
and yellow colors can be used outdoors up to one month.
• Embossed vinyl backing is easy to tear and conforms well to irregular surfaces.
Since it contains no cloth scrim, there are no exposed thread ends to wick water
into adhesive layer.
• If the adhesive side of the tape comes in contact with itself, it can be pulled apart
so the tape is not wasted.
• Typically used at room temperature, but will remove cleanly when applied to a
painted steel surface and heated up to 250°F (121°C) for up to one hour.
• Rubber adhesive sticks well to many substrates.
• Unwinds easily off the roll.
