Mesh Foil for window shielding

Mesh foil is a very fine electrically conductive wire mesh laminated between two layers of scratch-resistant transparent foil. The wires are so fine that they can hardly be seen with the naked eye. The product is very strong but it still bends easily. It is easy to apply Mesh foil onto glass, acrylic and polycarbonate either by hand or with a laminator. It can be supplied with or without self-adhesive. The foil is available in 3 different sheet styles. The maximum sheet/roll in width is approx 1035 mm.

• 1STD Mesh foil laminated between two layers of plastic
• 4BTB Mesh foil with 3-4 mm silver busbar at the top and bottom, laminated between two layers of plastic
• 5BAR Mesh foil with a 3-4 mm silver busbar all around, laminated between two layers of plastic

Turnkey windows

If you are interested in ready-made mesh-foil windows, please take a look at our EMI/RFI shielded mesh foil windows. Here the mesh foil is bonded between two layers of glass or plastic, or a single layer of mesh foil is fixed onto one side of a single glass or plastic window.

Mesh foil applications

Shielding displays, windows, touch screens, monitors, LCD screens and TEMPEST.

Options (on request)

• Stainless steel wire mesh
• Blackened copper wire mesh

Mesh foil options

High performance foil for windows & displays:

• No adhesive 9000 serie
• Transparent adhesive 9100 serie
• Scratch resistance 9200 serie
• Scratch resistance adhesive 9300 
• Micro suction silicone adhesive 91SUC 

Micro suction silicone adhesive

For easy manual application of the foil we have developed a new Micro Suction Silicone adhesive. This adhesive has a number of advantages that make the film easy to position. Our advise is to use standard adhesive only for laminating machines or very very experienced people. For all else use this Micro Suction Silicone Adhesive.

Benefits

• Reusable / Repositionable
• Never attach permanently
• Easy to apply by hand, less bubbly

Please note: Mesh foil with Micro Suction Silicone adhesive has a thickness of 450 micron / 0.45 mm.

The top layer can be affected by acids, for example from human skin. To protect the conductive layer, you can apply a transparent film or you can have the adhesive side facing out. Max. working temperature 60 ºC.

Wire-mesh angle

Mesh foil with moiré effect and without moiré effect

• The wire mesh can be placed at a custom angle to prevent the moiré effect on your display (standard is 0 degrees).
• A custom wire-mesh angle is only available with sheet styles 1 and 5

NOTE: For LCD displays, 17°, 35° or 45° are used typically. We recommend that you request a sample of the product to determine the proper angle of the wire mesh for your application.
