For noise countermeasures and radio wave absorption, use [Electromagnetic Wave Shielding Thermal Spray Coating].

For noise countermeasures and radio wave absorption, use [Electromagnetic Wave Shielding Thermal Spray Coating].

Shielding for resin housings and measures against 5G and millimeter-wave radar! Coating of complex-shaped housings is possible with spray-type thermal spraying.

Kodama's electromagnetic wave shielding thermal spray enables a wide range of shielding from low-frequency magnetic shielding to high-frequency electromagnetic wave absorption. We solve challenges with designs tailored to our customers' needs. We eliminate the issues associated with conventional aluminum enclosures and noise-absorbing sheets through thermal spray coatings, and further enable lightweight products with resin enclosures. 【Electromagnetic Wave Shielding Effect】 ■ Low-Frequency Noise Shielding - Our proprietary technology provides an attenuation effect of approximately 10 to 50 dB for low-frequency magnetic noise (KEC method). ■ Electromagnetic Wave Shielding - The shielding effect for near-field electric/magnetic fields is approximately 10 to 95 dB, - For far-field plane waves, it is approximately 95 to 120 dB. ■ High-Frequency Noise Countermeasure Area - At 29 GHz (Ka band), an absorption characteristic of approximately 18 dB, - At 85 GHz (W band), an absorption characteristic of 37 dB has been confirmed. *For more details, please refer to the PDF document or feel free to contact us.
