Morgan Advanced Ceramics Therm-O_Hot Patch ™ Cement
Categories: Ceramic; Oxide

Material Notes: Therm-O-Hot Patch is an ideal insulating material for fast, easy, refractory repairs. Therm-O-Hot Patch is composed of exfoliated vermiculite with binders and is a heat-set product. It has a service range to 1900°F (1038°C), is premixed and shipped in a five gallon pail. Therm-O-Hot Patch can be used for joints, cracks in walls, arches and furnace roofs to stop heat leaks. Therm-O-Hot Patch makes an excellent seal for “hot” walls, bulkheads and arches, minimizing cold air infiltration and conserving heat loss. Simply open the pail, and depending upon the method of application required, pump, caulk, spray, or trowel in place. Therm-O-Hot Patch will adhere well to all surfaces and dry quickly with minimal shrinkage. The product has excellent shelf life and if additional workability is needed, then water can be added and the product remixed.


  • On the spot repair jobs to side walls, end walls, ports or furnace roofs
  • A sealer for “hot” walls, bulkheads, and arches
  • Reduce cold air infiltration
  • Reduce heat loss
  • Good for expansion joint areas
