3M™ Performance Plus Duct Tape 8979 has a unique construction that allows for applications indoors and outdoors. Constructed of polyethylene film laminated to cloth with a rubber adhesive, this tape resists curling and tears off the roll cleanly for easy application on rough surfaces. 3M Performance Plus Duct Tape 8979 removes cleanly for up to six months from most opaque surfaces, even outdoor applications after sun and weather exposure. It sticks immediately and stays on for up to one year without deterioration. The tape was tested for flame spread using test method UL723, ASTM E84 and can be used at temperatures as high as 200°F for up to 30 minutes. This sturdy cloth-reinforced tape can be torn from the roll by hand and sticks instantly, providing a wide range of convenient solutions.
