ThermaCels

Hy-Tech insulating additive for paint and our line of ceramic, thermal insulating coatings are all based on tiny ceramic "microspheres". When these microspheres are combined with other materials they improve the thermal resistance of those materials. For instance, the ceramic tiles on the space shuttle fuselage use ceramic,degassed microspheres to control heat and reduce material expansion.

One single ceramic microsphere is so small that it looks to the naked eye as if it is a single grain of flour, (slightly thicker than a human hair). This tiny "bead" has a wall thickness about 1/10 of its diameter, a compressive strength range of 6500 - 60,000 psi, a softening point of about 1800° C. Insulating ceramics are fairly chemical resistant with a thermal conductivity of 0.1 W / m / Deg.C and they are non combustible. The hollow interior is a vacuum and physics law states that nothing can move by conduction through a vacuum, since it represents an absence of matter. In effect it is a miniature thermos bottle... a microscopic hollow vacuum sphere that resists thermal conductivity and suppresses sound.

In a bulk state, Hy-Tech ThermaCels Insulating Paint Additive looks like talcum powder.
The non-toxic powdered additive mixes in easily with any type of paint... interior, exterior, oil base, latex, ANY paint or coating.
When mixed into paint and applied the ceramic "beads" shrink down tight as the water and other vehicles evaporate creating a tightly packed film of the "thermos bottle" like cells. This ceramic layer provides a thermal barrier, improved fire resistance, protection from harmful UV rays, repulsion of insects such as termites and protection from the destructive forces of weather. Being a ceramic impregnated paint film, the durability of the dried paint film is improved tremendously, paints last longer and maintenance is minimized since the porcelain like surface film is resistant to staining. The roundness of the ceramics causes them to act like ball bearings, rolling upon each other, thus allowing the coatings to flow more easily.

	Conventional paint pigments are sharp edged and pack down loose as the paint film dries leaving paths for heat to pass through. The jagged edges also make for a rough surface which grabs dirt and soils easily.
	The ThermaCels ceramic microsphere blend creates a tightly packed dried film with minimal paths for heat transfer resulting in very efficient thermal barrier. The hard ceramic shell resists dirt.
