EmisshieldThe Next Generation of High Emissivity Coatings
Applied to refractory, ceramic fiber, or metal, Emisshield bonds with the surface to form a composite material that re-radiates heat back into your process instead of losing it to the walls.
01 · The Technology
Applied as a Coating. Performs as a Composite Material.
Emisshield is a family of high emissivity ceramic coatings, developed at NASA’s Ames Research Center for the X-33 and X-34 space vehicle programs. Applied at just 2–4 mils to the hot face of a furnace, it raises surface emissivity to 0.85–0.95 — and holds it there up to 3,100°F (1,700°C). It is not an insulator: it absorbs radiant and convective energy and re-radiates it directly to the cooler product load, so heat that would escape up the stack does work instead.

03 · How Emissivity Works
Absorb. Re-radiate. Perform.
Radiant energy from the heat source is absorbed into the Emisshield composite surface instead of soaking into the wall, then re-emitted onto the load. Re-radiated, not reflected: the same firing rate delivers more usable heat.
/ 01
Absorb
Radiant energy is taken into the composite surface instead of soaking into the wall. The coating becomes part of the surface itself.
/ 02
Re-radiate
The surface re-emits that energy onto the load. Re-radiated, not reflected, so heat returns to the product and process.
/ 03
Perform
Same firing rate, more usable heat: less fuel, more production, documented in service.

Common Questions
Frequently Asked Questions.
What is a high emissivity coating?
A thin ceramic coating engineered to raise a surface's emissivity close to black-body behavior (0.85–0.95) and keep it there at extreme temperature, so furnace surfaces re-radiate heat into the product instead of losing it.
How much fuel can a high emissivity coating save?
Documented Emisshield results range up to 15% depending on asset, fuel, and baseline condition — with specific audited cases at 5%, 8%, and 12%.
Is Emisshield an insulator?
No. Insulation resists heat flow; Emisshield redirects it — absorbing radiant and convective energy at the hot face and re-radiating it to the cooler product load. The two work together.
What temperatures can Emisshield withstand?
Emissivity holds constant to 3,100°F (1,700°C), with thermal shock tolerance from -392°F to 2,732°F in 3 seconds without failure.
