Sealing agents often cannot be prefabricated according to their shape and size in advance, so their processability is particularly important. Organic silicone sealants are widely used in the aerospace industry. Many aerospace products require long-term sealing to withstand 300 ℃, short-term sealing to withstand 400 ℃ or above, or instantaneous sealing to withstand 1000 ℃ or above.
At present, China has high-end single component and two-component PU sealants, mainly used for sealing waterproof electrical connectors, cable ends and plugs, circuit boards and other electrical components of aerospace products.
Although significant progress has been made in the development of adhesives for aerospace products, some key materials required by the aerospace industry still rely on imports, and the performance and quality of some materials are not yet stable. In the future, there will be many new demands for special adhesives in aerospace projects such as lunar exploration, long-term space stations, and deep space exploration, which require the continued efforts of scientific and technological workers engaged in adhesive preparation and application.
