Having worked in the aerospace industry for over 14 years, I am aware of some of the high tech coatings, films, etc. used to insulate or distribute heat. I stumbled across this site that is a NASA spinoff company, Hytechsales.com.
The microspheres in the HY-TECH insulating ceramic additive have compressive strengths up to 6,000 psi, a softening point of about 1800° C., and they are fairly chemical resistant, with low thermal conductivity of 0.1 W / m / Deg.C.
The scientific process went one step farther and improved on the ceramic microspheres by removing all the gas inside which created a vacuum. Physics law states that nothing can move by conduction through a vacuum, since it represents an absence of matter. In effect we have a miniature thermos bottle… a microscopic hollow vacuum sphere that resists thermal conductivity and reduces the transfer of sound.
When mixed into paint the painted surface dries to a tightly packed layer of the hard, hollow “microspheres”, ( Hy-Tech’s exclusive CVM, ceramic vacuum matrix technology.) The tightly packed film reflects and dissipates heat by minimizing the path for the transfer of heat. The ceramics are able to reflect, refract and block heat radiation (loss or gain) and dissipate heat rapidly preventing heat transfer through the coating with as much as 90% of solar infrared rays and 85% of ultra violet-rays being radiated back into the atmosphere.
