HLN-3500 High-Temperature Reflective Ceramic Coating
HLN-3500 High-Temperature Reflective Ceramic Coating is a special energy-saving coating with high-temperature resistance, strong reflectivity, low thermal absorption, excellent corrosion resistance, and high wear resistance. It is formulated using a special inorganic silicate composite system as the film-forming material, with the addition of transition metal oxide, zirconium oxide, rare earth oxide Y2O3, and other fillers.
The cured coating forms a dense ceramic radiative layer with a good, high, and stable infrared emissivity. In environments above 800°C, the coating improves heat exchange inside the furnace, enhances combustion temperature and uniformity within the furnace chamber, allowing for more efficient fuel combustion. This, in turn, increases the thermal efficiency of refractory materials, reduces energy consumption, conserves energy, and extends the service life of furnace linings.
