Ancor Emergency Repair Tape adheres to its own rules. It only adheres to itself. Apply it under tension and youll never have the sticky residue or ordinary tape. Also unlike basic roll tape, Ancor Emergency Repair Tape stretches up to 300% its original length and boasts a 60 ppi tear strength to perform well even at several times its starting length. As one of the strongest tapes on the market, this innovative tape forms a permanent air- and watertight seal, has excellent UV resistance, and begins to bond immediately on contact with itself.
