Contributing to weight reduction! High-performance electromagnetic shielding coating that meets the needs of the automotive industry.
"PROCEM" is a conductive multilayer metal film designed to impart electromagnetic shielding functionality to polymers and composite materials. As a PVD (Physical Vapor Deposition) coating, "PROCEM" not only offers the advantage of providing electromagnetic shielding but also simultaneously addresses issues such as dimensional and weight changes of the housing before and after coating, as well as the finish quality of masked areas. "PROCEM" meets the needs of the increasingly electronic automotive industry. 【Features】 ○ Contributes to weight reduction ○ Directly coats a complete metal thin film onto resin housings ○ Meets electromagnetic shielding specifications for automotive electrical equipment ○ Higher performance than conventional electromagnetic shielding paints ○ Mass production track record at European factories For more details, please contact us or download the catalog.
