Preventing malfunction of electric equipment
Electromagnetic Wave Shield Coatings
Overview
Geomatec's electro-magnetic wave shield coatings reduce electromagnetic waves coming from transparent surfaces such as display cover panels or automobile rooftop windows.
Transparent conductive films enhance transparency, and light-shielding coatings suppress glare. It is also thinner than other electro-magnetic wave shields that use common plating processes.
Features & Strengths
Point1 Amazing shield effectiveness while maintaining transparency
With transparent conductive films, we have achieved 85% transmittance of light at all wavelengths with high shielding 20dB and greater. These films are also effective at repelling heat rays.
Point2 They can be coated to magnetic material as well
Magnetic objects such as Ni or Fe can also be thinly coated. In addition, by applying blackened film coatings over the metallic thin films, it is possible to reduce the glare of metallic luster.
Point3 Can be applied to substrates made from a wide variety of material types
Can be coated to many substrates, including glass, ceramic, resins, and more.
Applications
Cover panels for aircraft instruments & Displays
Preserve visibility of display devices and maintain normal instrument operation to ensure a safe, stress-free flight

Rooftop windows (sun roofs & moon roofs)
By applying our electro-magnetic wave shields to rooftop windows, drivers can block incoming electromagnetic waves and make it easier to operate their onboard electronic devices. Geomatec also makes it is possible to directly coat resin roof materials such as polypropylene (PP), which is difficult to plate.

Laptop computers & FA devices
Due to the light weight of laptop computers and portable FA devices, resins are increasingly used in the place of metals not only in casings but also interiors.
By directly coating resins with metallic films, these lightweight materials gain shielding effects.
This has contributed to lighter weight terminals and malfunction prevention.
