Unikote M is a refractory coating material designed to provide a protective surface layer over ceramic fiber modules.
Unikote M is for medium to high temperature, gas fired furnaces where contaminants are not severe.


Refractory coating material


  • Applied over weld on or veneering modules hot face surface
  • Used to reduce airbron fiber or other refractory particles


Unikote M” is applied to the Module hot face surface either by spraying (or) brushing. It is supplied in a dry state and then mixed approximately 55% weight by water. The slurry should be roughly agitated with a power drill motor until complete mixing is achieved. The solids portion will have a tendency to settle down, brief agitation may be necessary. After installation it is recommended that UNIKOTE is allowed to air dry 24 hrs before the furnace is fired.


  • Easily applied over weld or Module hot face and furnace top floors
  • Adhere readily to fiber modules during the thermal cycling process
  • Reduces module shrinkage by keeping the hot face “tight”
  • Guards the ceramic fiber Module against metal oxide, chemical and contaminant attack
  • Protects against the velocity damage and erosion from particulate matter
  • Excellent resistance to chemical attack exceptions includes hydrochloric acid, Phosphoric acid and strong alkalies
