High temp Heat-Setting Thermal Ceramic Brick

Note: This is a variation of Thermal Ceramics Brick Mortars (2850ºF – 3200ºF Range).


  • Matched for use with each Thermal Ceramics firebrick and insulating firebrick
  • Both heat-setting and air-setting grades are available
  • Temperature use limits range from 2850ºF to 3200ºF

Thermal Ceramics refractory mortars were developed to match Thermal Ceramics dense and insulating firebricks in various thermal, chemical, and physical service conditions. Available in wet ancell namery grades, Thermal Ceramics mortars will provide the convenience you want with the performance you need for practically every high-temperature refractory application. K®-Bond Mortar has an extra smooth, creamy consistency plus excellent tackiness to brick surfaces.
