  • Patent number: 6521309
    Abstract: A double-sided single-liner pressure-sensitive adhesive tape has a first pressure-sensitive adhesive, preferably an acrylic pressure-sensitive adhesive, on one side of a carrier web, and a silicone pressure-sensitive adhesive on the other side of the carrier web. The tape is single-liner in that a double-sided release liner is wound with the double-sided tape, such that only a single release liner is required. A layer of first release material, preferably a silicone release material, is disposed on a first side of a release liner web facing the acrylic or other first pressure-sensitive adhesive. Fluorosilicone release material is disposed on the opposite surface of the release liner web facing the silicone pressure-sensitive adhesive. Preferred embodiments exhibit fluorosilicone unwind along with good balance of tack, adhesion and shear.
