Henkel AG anchors its position through adhesive-conductive hybrid chemistries that bond and shield simultaneously. DuPont (Laird Performance Materials) specializes in multi-layer laminate structures that absorb broadband interference across EV frequency ranges.

Electromagnetic and radio frequency interference coating for electric vehicles comprises thin-film or spray-applied barrier materials—typically silver-, nickel-, or carbon-based composites with thicknesses from 25 to 200 microns—that attenuate electromagnetic emissions from 30 MHz to 6 GHz. These coatings prevent crosstalk between high-voltage inverters, battery management systems, and wireless communication modules. Conductive coatings currently dominate value capture due to their established supply chains and proven attenuation performance above 60 dB. Battery enclosure applications are expanding fastest as cell-to-pack architectures expose larger conductive surfaces to radiated emissions. OEMs represent the most concentrated end-user margin pool, with fleet operators emerging as a secondary growth channel through retrofit programs.
