ECCOSORB® Coating 300 is a two-part polyurethane, high loss absorber coating that is heavily loaded with iron filler for 1-18 GHz. It is a thixotropic coating that can be brushed or sprayed using common spray equipment.
ECCOSORB® Coating 300 is designed for use on compound surfaces where flat sheet elastomer or foam absorbers are not desirable. It can reduce the radar cross section of objects, reduce false echo or ghost images on a ships radar, and attenuate surface currents that are generated by radiation impinging on metal surfaces. To operate as a specular absorber such that resonant absorption at a particular frequency is obtained, it is necessary for the ECCOSORB® Coating 300 to be bonded to a metal surface. The overall thickness of the coating is critical to performance as a specular absorber and is attained through applying several layers until the desired performance is achieved.
