High-temperature resistant thermal insulating coating is one sort of the aerospace energy-conserving resistant thermal insulating coatings which consist of the type of high-temperature coatingthe type of the room-temperature coating. The high-temperature resistant thermal insulating coating, which is the pioneer in the world, is inorganic mono-componentfree of bad odors. The scope of temperature resistance is from-80℃ to 1500℃,the heat conductivity is only 0.03W/m.K. therefore, it can inhibitshield the radiant heat of infrared raythe heat transfer efficiently. The efficiency of thermal insulationinhibition is up to about 90%. It can inhibit the heat radiationheat diffusion from the high-temperature object. And to the low-temperature object, it can keep cool efficientlyinhibit the cold loss caused by radiating-heat of the environment,also it can prevent the object from condensation.
