Overview
The white paper titled "Adhesives for Cryogenic Applications" by Master Bond Inc. discusses the critical role of adhesives in environments subjected to extreme low temperatures, particularly in aerospace and high-energy physics applications. It highlights the challenges faced in these settings, such as maintaining bond strength and stability under cryogenic conditions and high vibrational forces.
The document presents various case studies demonstrating the successful application of Master Bond's epoxy systems in cryogenic environments. One notable example is the bonding of aluminum and Inconel components in NASA's Alpha Magnetic Spectrometer (AMS-02), where the adhesives needed to withstand temperatures as low as -252°C while ensuring thermal conductivity and compatibility with materials that have different thermal expansion coefficients.
The paper emphasizes the importance of low outgassing properties in adhesives used for space applications, as outgassed compounds can contaminate sensitive instruments. For instance, the Master Bond EP21TCHT-1 epoxy was utilized to attach a hydrazine chemiresistor sensor, ensuring reliable performance without compromising measurement accuracy.
Additionally, the white paper discusses the use of the Master Bond EP29LPSP epoxy system, which meets the requirements for cryogenic performance and bond strength necessary to endure the high vibrations experienced in rocket engines. The document also touches on the significance of electrical conductivity in certain applications, such as electrohydrodynamic conduction pumps used in satellite cooling systems.
Overall, the white paper serves as a comprehensive resource for understanding the unique requirements and solutions for adhesive applications in cryogenic environments, showcasing Master Bond's expertise in developing specialized epoxy systems that meet the demanding needs of modern aerospace and scientific research.
