I'm thinking of just painting the entire house in this stuff....NOT.

    Subject: Frequency coverage and cost

    The web site documents list attenuation only up to 2000 MHz.

    Are the coatings usable at 2.5 and 5.8 GHz ?

    Please provide an approximate cost in small quantities sufficient to
    coat a single 20x20x10' room, or a 100x300x30' warehouse.

    Do you have a transparent solution for windows?

    I got a reply from sales that they had forwarded my request to their technical department and one of their engineers would reply.

  • Regarding the emsec coating:

    I have engineering samples of RF absorbent material up to 1/2" thick from other companies. It doesn't have the 60-70 dB attenuation listed for this emsec coating, one type of which is only 6 mil dry film thickness.

    Although it is just speculation on my part, I would think to get attenuation this good, the coating has to be very RF opaque/reflective. I don't know what that would do to systems operating inside, but I expect the multipath would be pretty bad.
