Thermal Coatings

FHL® Emiglaze — High-Emissivity Thermal Coating

High-emissivity coating that upgrades existing linings — more heat to the load, less to the walls.

FHL® Emiglaze is a high-emissivity thermal coating for energy saving in high-temperature applications. Applied to refractory or ceramic fiber surfaces, it raises the surface emissivity of furnace walls so they re-radiate more heat back to the workload instead of absorbing and conducting it away.

FHL® Emiglaze high-emissivity thermal coating for furnaces High-temperature duty

Key features

High-emissivity surface — walls re-radiate heat to the load

Measurable energy savings in high-temperature furnaces

Improves temperature uniformity across the chamber

Seals and hardens ceramic fiber surfaces — less erosion & dusting

Fast retrofit on existing refractory or fiber linings

Ideal finishing coat over FHL-VAC® modules

The coating also seals and hardens fiber surfaces, reducing erosion and dusting. It is one of the fastest, most economical retrofits for improving thermal efficiency and temperature uniformity in existing furnaces — and the ideal finishing layer over FHL-VAC® module linings.
