In February 2026, the cognitive misunderstanding about high-temperature resistant paint has attracted industry attention. Many customers and designers often require high-temperature resistant paint to be flexibly colored like polyurethane topcoat, and even mark non-aluminum national standard or RAL color numbers, which actually exposes the misunderstanding of its essence. Ordinary paint relies on a complete organic resin structure to wrap pigments to achieve various stable colors, but the organic structure begins to age at 200-300℃ and decomposes above 300℃, restricted by the physical limit of materials. In order to cope with high temperatures, high-temperature resistant paint needs to go through the process of decomposition and volatilization of organic components and structural rearrangement, and finally form a ceramic-like protective layer mainly composed of siloxane structure and inorganic fillers, which really plays a role only after "being burned". The higher the temperature, the fewer color choices there are for high-temperature resistant paint. Organic pigments will be burned at high temperatures, and most inorganic pigments are prone to discoloration and failure. Only aluminum color has become a "survivor" after material selection because it is high-temperature resistant, can form a protective film and has physical barrier properties. Insiders emphasize that the real high-temperature protective system has sacrificed "aesthetics" to ensure performance, and its core function is to extend the service life of steel in extreme environments.
