Antistatic Grade / Clean antistatic grade, which is a thin film and maintains stable conductivity

We offer solutions for the following problems.

  • Dust sticks to the products due to static electricity...
  • Static electricity caused by peeling off the film damages the products...
  • Possibility of sparks/ignition when the film is peeled off ...
  • Products build up static electricity when they are being used, which causes frequent malfunctions...

Key features of antistatic grade

Transparency

Just 0.03 µm thick, transparent film

Its high conductivity and the excellent uniformity of the film thickness lead to adequate antistatic performance (surface resistivity of 104 to 109Ω/sq), even when it is in the form of ultra-thin film whose thickness is on the order of nanometers.

Its high transparency, which is even good for optical film, can be maintained. The necessary quantity is low, which reduces material costs.

Conductivity with no dependence on humidity

Even at low temperatures and 20% RH

Unlike ionic conductive surfactants whose conductivity is achieved by absorbing water from the air, this grade's mechanism for conducting electricity enables stable conductivity independent of environmental humidity.

There is no need to worry about using it even in a low-humidity environment in the winter, an arid region, or a cleanroom where humidity control is difficult.

General-purpose processes

Antistatic measures consisting of just coating and drying.

Suitable for various general-purpose wet coaters such as gravure coaters and die coaters.
Use Denatron that is highly diluted with alcohol for easier drying. Add antistatic properties to your products yet maintain high productivity.

Ecology

Water-based coating material that is eco/human-friendly.

Water-based coating material that is eco/human-friendly.

As Denatron is a water- or water/alcohol-based coating materials, it is a coating agent that mitigates environmental burdens.

Leveraging its water-based characteristics, you can apply it in inline coating processes, which use heat generated during the film production process to dry the coating for energy savings. The coating is also flexible enough to extend as the film stretches.
