Eccosorb®Coating 300
Two part Polyurethane Coating
TWO PART POLYURETHANE COATING
Eccosorb Coating 300 is a two-part polyurethane coating that is heavily loaded with iron to
provide its absorbing characteristics. It is a thixotropic coating that can be brushed on or sprayed
on using common spray equipment.

• Eccosorb Coating 300 is designed to reduce the radar cross section of objects, to reduce false
echo or ghost images on ship radar, and to attenuate surface currents that are generated by
radiation impinging on metal surfaces.
• Eccosorb Coating 300 is designed for use on compound surfaces where flat sheet elastomer or
foam absorbers are not desirable.
• 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 perform as a specular absorber and is attained by
applying several layers until the desired performance is achieved.
