I. Key performance parameters: This coating has an infrared emissivity of up to 0.92ε in the 0.5–13.5 μm wavelength range. The thermal conductivity of some of these products is as low as 0.03 W/m·K. Their temperature tolerance ranges from -50°C to 600°C. Additionally, they possess waterproof, moisture-resistant, insulating, and anti-corrosive properties, allowing them to function properly in vacuum environments. II. Composition of typical formulations: The film-forming matrix is usually made from bisphenol A epoxy resins or modified silicone rubbers; in some formulations, water-based polyurethanes are used as a carrier to ensure good adhesion and weather resistance. Functional fillers: Nanotube carbon and spinel metal oxides are added to achieve high thermal conductivity and high radiation resistance; boron carbide and nano-CeO₂ are used to enhance radiation tolerance, while graphene is included in some formulations to improve the toughness of the coating. III. Main application scenarios: In addition to water-cooled reactor nuclear facilities, it can also be widely used in electronic and electrical devices for heat dissipation, industrial high-temperature equipment, building insulation layers, etc. Within the nuclear containment structure, it provides multiple protective functions such as radiation resistance and moisture conduction. IV. Conventional construction methods: Various application techniques such as brushing, spraying, and dipping can be used. Two-component products are applied after being mixed in the correct proportions; upon curing, they form a fish-scale-like microstructure that further enhances thermal radiation efficiency. The application process is simple and no special pretreatment is required.
