Sealants
In space and astronautical engineering, sealants are materials used to prevent the leakage of fluids or gases between two surfaces. They are commonly used in spacecraft and launch vehicles to seal joints, seams, and other connections to maintain pressure and prevent contamination. Sealants can be made of various materials such as silicone, epoxy, and polyurethane, and are designed to withstand extreme temperatures, radiation, and vacuum conditions. The application of sealants requires careful surface preparation and precise application techniques to ensure a reliable and durable seal. In addition to their use in spacecraft and launch vehicles, sealants are also used in space suits, habitats, and other space-related equipment.
