Modern industrial thermal facilities require proactive, fast-acting maintenance solutions that keep furnaces in service without demanding expensive, full-scale lining demolition. Highland Refractory's High Temperature Mending Materials Series integrates two complementary monolithic product lines: Structural Refractory Repair Materials for restoring damaged masonry cavities, and High Emissivity Ceramic Coatings for thermal radiation enhancement and hot-face sealing.
Engineered for metallurgy ladles, cement rotary kilns, petrochemical heaters, and ceramic tunnel kilns operating between 1200°C and 1800°C, this unified product family allows maintenance managers to address both physical spalling and thermal inefficiency simultaneously. By combining deep-cavity patching with radiative surface glazing, plant operators can extend existing refractory lining campaigns by 6 to 18 months, eliminate casing hot spots, and lower overall fuel consumption by 5% to 15%.
High emissivity coating is a specialized high-temperature ceramic slurry engineered to enhance radiative heat transfer and reinforce refractory linings in industrial furnaces, kilns, and fired heaters. Formulated with high-emissivity inorganic oxide complexes (including selected zirconium, silicon carbide, and specialized spinel phases), Highland Refractory’s high emissivity coatings convert low-emissivity refractory surfaces into highly radiative thermal radiating bodies. Applied directly onto dense refractory bricks, insulating firebricks (IFB), or ceramic fiber modules, our high emissivity ceramic coating elevates surface emissivity to ≥ 0.92 across broad thermal radiation wavelengths. This structural radiation enhancement enables industrial heating systems to transfer radiant heat more uniformly into process loads, shorten heating ramp-up intervals, reduce flue gas exhaust temperatures, and shield underlying refractory linings against thermal shock, chemical vapor penetration, and high-velocity gas dusting.
High temperature and high strength repair material is a special material used to repair equipment and structures in high temperature environments.

Select the specialized solution engineered for your furnace maintenance objective:
High-alumina, corundum, and silicon carbide-fortified patching compounds designed to fill cracks, ram deep spalling gouges, and repair burner quarls without wooden formwork.
Liquid-applied inorganic microcrystalline slurries that permanently boost hot-face thermal radiation emissivity (ε ≥ 0.92) while sealing refractory surfaces against chemical and vapor erosion.
Traditional furnace maintenance often treats physical lining spalling and thermal inefficiency as separate issues. Highland Refractory engineers an integrated two-step restoration method that delivers superior structural protection and measurable thermal optimization:
Chiseled cavities, open masonry joints, and slag-eroded sections are patched in-situ using moldable TX Series plastics or rapid-bonding patching mortars.
Result: Wall geometry and mechanical refractory thickness are restored within hours, preventing localized steel shell hot spots and flue gas breakthrough.
Once structural patches achieve initial ambient set, a uniform coat of HEC High Emissivity Slurry is sprayed across both the newly repaired areas and surrounding aged refractories.
Result: The coating creates an impermeable microcrystalline glaze that seals boundary joint pores, hardens fiber surfaces, and lifts radiant heat flux (ε ≥ 0.92) across the entire furnace chamber.
Use the following diagnostic matrix to identify whether your equipment requires targeted physical repair, radiative surface spraying, or an integrated combined treatment:
| Observed Furnace Symptom | Primary Root Mechanism | Recommended Material Package | Primary Operational Benefit |
|---|---|---|---|
| Localized Brick Spalling / Deep Wall Gouges | Thermal shock cracking & mechanical impact | Highland TX-1 / TX-1A Plastics | Restores lining thickness without mold rigging |
| Ladle Slag Line Scour & Molten Metal Erosion | Basic slag chemistry & turbulent molten fluid | Highland TX-2 (SiC + C Fortified) | Resists slag wetting; adds 15–25 ladle heats |
| High Fuel Bills & Elevated Flue Gas Temperature | Aged refractory radiation emissivity degradation | HEC High Emissivity Coating | Enhances radiant heat transfer; 5%–15% fuel cut |
| Ceramic Fiber Surface Flaking & Velocity Dusting | High burner velocity (> 25 m/s) wind erosion | HEC-1400 Fiber Mastic Formulation | Hardens fiber skin up to 35 m/s air velocity |
| Major Scheduled Turnaround Refurbishment | Combined brick cracking, erosion & heat loss | Integrated Package (TX + HEC) | Full chamber structural & thermal restoration |
As an actual manufacturer based in Zhengzhou, China, Highland Refractory provides streamlined procurement logistics for global plant engineers and maintenance contractors. Both product lines share compatible packaging standards:
25 kg carton boxes (poly-lined pre-tempered plastic slabs) or 25 kg airtight pails. Moisture-sealed for a guaranteed 6-month shelf life.
25 kg plastic pails or 250 kg steel drums containing pre-mixed liquid slurries. Free from hazardous VOCs, stable for 12 months under frost-free conditions.
Buyers can combine TX repair compounds and HEC coatings onto single fumigation-free export pallets (approx. 500 – 1000 kg), sharing a single minimum order quantity.
Inspect the physical integrity of the refractory hot face: If there are open cracks larger than 5 mm, localized spalling pockets, or molten metal gouges deeper than 10 mm, you must first restore structural thickness using TX Series Repair Materials. If the masonry or fiber modules remain structurally intact but suffer from elevated fuel consumption, uneven chamber heating, or light surface dusting, spraying HEC High Emissivity Coating directly is sufficient to optimize performance.
We recommend allowing TX patching compounds to achieve initial ambient air dry for 6 to 12 hours so the surface skin hardens sufficiently. Once firm to the touch, HEC coating can be sprayed directly over both the repair patch and adjacent parent refractories. The two materials will co-sinter seamlessly during the subsequent initial heating ramp.
Yes. Highland Refractory supports consolidated maintenance pallet shipments. For example, a single export pallet can be configured with 10 pails of TX repair plastic (250 kg) and 10 pails of HEC ceramic coating (250 kg), fully qualifying for our standard 1-pallet minimum order quantity (MOQ: 500 kg).
Yes. Simply provide your furnace internal chamber dimensions (length, width, height, or diameter), operating temperatures, fuel type, and an estimate of damaged surface area. Highland's thermal engineering department will provide a complete bill of materials, including calculated pail counts for both patching compound and coating coverage.
