Abstract

In Part I of this article, complex dielectric constant values in the frequency range of 24 through 34 GHz were presented for paints and primers currently being used as well as for candidate replacements. Tables of complex dielectric constant values were given for (1) Triangle no. 6 white flat paint, (2) zinc chromate primer, (3) 18FHR6 white water-based paint, and (4) 283 water-based (Aquapoxy) primer. In this article, Part II, complex dielectric constants are presented for 500FHR6 acrylic urethane-based paint and Triangle no. 710 white glossy paint. In addition, this article gives plots of the real part of the complex dielectric constants and loss tangents of most of the above-mentioned paints and primers. These plots enable quick comparisons to be made of the dielectric properties of the paints and primers in the region of 32 GHz. A final part of the paint study, to be done in the near future, will be to use these complex dielectric constants to compute noise-temperature degradations that occur when various paints and primers are applied to antenna reflector surfaces.
