Cactus® Y291M Double-Coated PET Film Tape with Differential Adhesion – 1.0 mil polyester (PET) film coated on both sides with pressure-sensitive acrylic adhesive. One side (exposed side) provides moderate adhesion and good initial tack allowing immediate/permanent bond to a variety of surfaces (including irregular and porous surfaces). The closed (liner) side offers a lower tack acrylic for clean removal from most surfaces. Features an easy release PCK liner 76# (white). APPLICATION: Mounting posters, signs, banners or other items which use light duty bonding but need to be removed without residue. Temporary bonding of protective foam or film.
