"EMI shielding film" to prevent malfunction of electronic devices.
■Overview EMI shielding film using transparent conductive films and metal thin films. It is possible to create a transparent EMI shield using transparent conductive films. A thinner metal thin film than plating can be used to produce an EMI shield that suppresses the metallic luster "glare."

basic information
■Features and Strengths - Excellent shielding effect despite being transparent Achieves a high shielding effectiveness of over 20dB with an 85% total light transmittance using a transparent conductive film. Additionally, it has the effect of reflecting thermal rays. - Capable of coating magnetic materials Can thinly coat magnetic materials such as Ni and Fe. Furthermore, by coating a black film over a metallic thin film, it suppresses the "glare" of metallic luster. - Compatible with various substrate materials Can be coated on various substrates such as glass, ceramics, and resins.

Applications/Examples of results
- Aircraft instruments and displays Shielding electromagnetic waves generated from display devices to prevent interference with instruments and computers. - Rooftop glass (sunroof, moonroof) Applying "EMI shielding" to rooftop glass to prevent electromagnetic waves, contributing to the stable operation of electronic devices inside the vehicle. Additionally, Geomatic can directly coat resin roofs, such as polypropylene (PP), which are difficult to process with plating. - Notebook PCs and FA equipment To reduce weight, not only the casing but also the metal plates used internally are being replaced with resin. By directly coating a metal film on the resin, a shielding effect is achieved.
