About Dynacote Thermal Protective Coatings

Dynacote Thermal Protective Coatings with Emisshield™ will serve the fireplace, chimney and venting industry as well as the barbeque and accessories markets by keeping heat where it belongs offering tremendous benefits which improve the transfer of radiant heat. These benefits include increased efficiency, decreased emissions, prolonged substrate life, increased abrasion resistance and valuable energy savings.

This explanation of how emissivity works appeared in the May, 2002, edition of Ceramic Industry Magazine written by Christine L. Grahl:

"Emissivity is the ability to absorb energy and subsequently release that energy back out from the surface. . . . emissivity is also a function of temperature - the coating's performance actually increases in hotter temperatures. Once the coating has dried, some of the ceramic material migrates to the surface, enclosing the emissivity agent. As radiant heat waves bombard the surface of the coating, the waves bounce around the ceramic molecules and are then absorbed by the emissivity agent. The energy imparted on these molecules causes them to vibrate. The higher the temperature, the faster the vibration of the molecules, and thus, the more effective the thermal barrier because less heat is transferred to the underlying material.

The coating also decreases the catalytic efficiency of the surface, resulting in a decreased surface temperature and protecting the underlying substrate from heat-related damage. Additionally, because less energy is transferred to the substrate, the coating increases the efficiency of the system by preventing heat transfer and dissipation. And because the coating was originally developed for extreme speeds (up to 14,000 miles per hour) in space applications, it is extremely resistant to wear and abrasion."

Emisshield™ Coatings are water based coatings that are 99.9% inorganic. They are applied using a standard spray gun and dry to the touch within thirty minutes. The coatings will range in color from light gray to dark black depending on the curing process required. The coatings can be applied to both metal substrates and ceramic-like substrates. Coating thickness will range from 3-7 mils, depending on substrate.

The Emisshield™ Coatings are ceramic in nature and are therefore inevitably resistant to acid and chemical attack. The Metal Coatings are unique in that they are pinhole-free after being through a curing process; the cured coatings do not allow the acids and chemicals to penetrate its surface to begin attacking the metal beneath. Although not pinhole-free, the Emisshield™ Ceramic Coatings will help fill in the pores of ceramic-like materials and help seal the surface.
