Yigal,
Do you know anything about the CeRam Kote 54 mentioned below?
Would your preceramic polymer coating be useful for the coating epoxy or
other RP models for the purposes of testing?

Brock,
I heard about it before but with not many details. We also did some
technology assessment evaluation (literature) for similar types of advanced
coatings. The CeRam-Kote is actually an epoxy filled with ceramic
particles. The use of filled epoxy resin paints is definitely not new but the type
of particles, particle preformulation treatment, or even the type of the
epoxy may provide unique properties. We are working or a
similar-but-different approach in which we are using ceramic fillers and preceramic
polymer as the resin instead of epoxy. We have not used it for coating epoxy
thus far, but for coating metals, such as steel and aluminum. The behavior
under supersonic pressure conditions is unknown. If you are interested in
technology assessment or development of such coatings we will be glad to
help!
