Chemical solvents are used in the defence industry for various purposes, including cleaning and degreasing equipment, manufacturing, and maintenance. They help remove oils, greases, resins, and other contaminants from machinery, weapon systems, and electronic components to ensure proper functioning and safety. Additionally, they are used in the production of explosives and propellants, as well as in surface preparation for coating and painting processes. Due to their effectiveness, these chemicals play a critical role in maintaining the reliability and performance of defence-related equipment and materials.
