Aerospace adhesives

Aerospace adhesives are special adhesives used in various applications in the aerospace industry. They need to have special properties such as high temperature resistance, low temperature resistance, radiation resistance, vacuum resistance, vibration resistance, etc. to ensure the stable operation of aerospace vehicles in complex environments. Common aerospace adhesives include phenolic-acetal, phenolic-nitrile, phenolic-epoxy adhesives and other first-generation acrylate adhesives, as well as second-generation acrylate adhesives .

　　Aerospace adhesives are adhesives specifically designed for use in aerospace applications, featuring high temperature, high strength, and low volatility to meet the special requirements and stringent performance standards of aerospace applications. Aerospace adhesives are widely used in aircraft, rockets, satellites and other carriers and their components manufacturing and maintenance of aerospace adhesives in the main features and way include:

　　1, high temperature performance: aerospace field often face high temperature environment, aerospace adhesives can maintain stable bonding strength and aging resistance at high temperatures.

　　2, low volatility: spacecraft require adhesives in the true environment, so aviation and aerospace adhesives usually have low volatility, so as to avoid the impact of volatiles on the performance of equipment.

　　3, high strength bonding: aerospace adhesives can usually provide high strength bonding to ensure that the spacecraft in flight over the structural safety and stability.

　　4, corrosion resistance: spacecraft often come into contact with a variety of chemical substances, aerospace adhesives need to have corrosion resistance, enough to resist the erosion of chemical substances on the bonding parts.

　　5、Low weight: Aerospace adhesives usually pursue low density to reduce the weight of the carrier and improve the load capacity and fuel efficiency.

　　Specific types of aerospace adhesives and methods of use will vary according to specific application requirements. For example, common aerospace adhesives include epoxy adhesives, ammonia adhesives, and acrylic adhesives. When using aerospace adhesives, relevant specifications and safety are strictly followed to ensure bonding quality and reliability.
