Abstract:

The object of this study is the development of a conductive white coating paint primarily for use on aircraft radomes. Two problems are addressed. First, in order to maintain a low pigment volume concentration PVC so the coating will have good erosion resistance, we have examined ways of inducing the pigment to flocculate in a chain or snowflake structure. This structure is needed to maintain interparticle contacts, and thus high conductance, while permitting a low PVC. The most effective way found to induce chain flocculation was with an applied electric field. With the flocs thus formed, they were cemented into permanent units with a SiCl4 treatment. The second problem examined was the preparation of a white pigment with a stable conductance showing resistance to oxidation. It is pointed out that more work on this latter problem is needed before a completely satisfactory paint is developed.
