Applying the film - step by step

Step 1

  • Measure the usable area
  • Cut the foil to size, adding 2 cm on each side (the extra will be cut off afterwards).

Step 2

  • Moisten the surface to which the foil will be applied with water from a spray bottle. The surface should be wet during the entire application process.

Step 3

  • Stick a piece of adhesive tape on one edge of the foil to easily pull off the transparent protection film.
  • Moisten the adhesive on the foil with the spray bottle.

Step 4

  • Carefully apply the wet, sticky side of the foil to the wet surface. It is important that both sides are moist.
  • Smooth the film carefully to avoid creases or bubbles.
Advantages
  • High tear strength, clear and adhesive-backed polyester film
  • Permanently electrostatic-dissipative coating
  • Complies with EN 61340-5-1
  • Humidity independent
  • Very low tribocharge generation and excellent electrostatic decay performance
  • High clarity, good chemical and abrasion resistance
  • Ideal for PCB manufacturing and testing
  • Suitable for clean manufacturing applications (retrofitting cleanroom windows, etc.)
  • Can be used as transparency for copies
  • Thickness: 0.1 mm
  • Maximum sheet/roll width: 1220 mm

Micro Suction Silicone adhesive

For easy manual application of the foil, we have developed a 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 for very experienced people, else use this Micro Suction Silicone Adhesive

Benefits

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

Please note: ESD foil with Micro Suction Silicone adhesive has a thickness of 230 micron / 0.23 mm.

Please note: in exceptional cases, the top layer can be affected by acids, for example from the human skin. To protect the conductive layer, you can apply a transparent film or use the adhesive side on top.
