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 and licensed exclusively to Emisshield, Inc. in 2001. Applied at 2 to 4 mils to the hot face of a heater, boiler, kiln, furnace, or component, it raises surface emissivity to 0.85 to 0.95 and holds it there 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.

02 · Products

One Technology. A Coating Engineered for Every Substrate.

  • Metal-substrate coatings.

    Radiant tubes, burner tips, rolls, water-cooled panels, structural steel, flare tips.

  • Refractory coatings.

    Brick, castable, and precast linings of heaters, kilns, boilers, and reactors.

  • Ceramic fiber and IFB coatings.

    Modules, blanket, and insulating firebrick, with shrinkage held under 1% in service.

40+ formulations since licensing the NASA technology. Every application is matched to substrate, atmosphere, and operating temperature.

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.

  1. / 01

    Absorb

    Radiant energy is taken into the composite surface instead of soaking into the wall. The coating becomes part of the surface itself.

  2. / 02

    Re-radiate

    The surface re-emits that energy onto the load. Re-radiated, not reflected, so heat returns to the product and process.

  3. / 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.
