P-11 / P-11L

ALUMINUM FOIL TAPE P11 is a solvent resistant, dead soft aluminum foil tape with a high performance acrylic adhesive engineered for a wide range of aerospace and industrial applications.

  • Aggressive, custom-formulated adhesive adheres tightly when smoothed down on work surfaces.
  • Permits clean and easy removal, with no residue.
  • Dead soft aluminum foil backing provides excellent conformability and solvent resistance.
  • Easy to handle, easy to apply and readily conforms to irregular surfaces.
  • Acrylic adhesive/foil backing construction makes for a vapor-tight seal that effectively combats moisture, contamination and corrosion.
  • Aging is practically non-existent because of the inherent stability of aluminum foil.
  • P11L offers a paper liner for ease of use when working with wide widths or die cutting precision part, such as window masks.

  • During aircraft stripping work, P-11 is used as a window mask and protective covering of critical parts against stripping compounds.
  • Also used as a mask in paint stripping and electro-plating operations...and for sealing duct joints in heating and air-conditioning systems.
  • In its interlined version, P-11L can be die cut to meet the exact dimensions of aircraft windows.
  • P-11 offers the ultimate in moisture vapor protection. Highly recommended for waterproof sealing if drums and canisters, edge sealing of double-pane thermo windows, and, for heat shielding and elimination of "hot spots" in small applications.
  • Also used to hold protective drapes in place during stripping, and to form a trough for diverting the wash-off of paints and chemicals.
  • In the refrigerator industry, P-11 is used as a condenser and evaporator fastener.
