👉 A protecting fluid, often referred to as a sealant or barrier fluid, is a specialized liquid used to create a protective layer between two surfaces that need to be sealed or joined, preventing the passage of liquids, gases, or contaminants. This fluid is crucial in applications such as welding, sealing joints in pipes, and protecting sensitive electronics from moisture or corrosive substances. By forming a thin, impermeable film, the protecting fluid ensures that the surfaces remain isolated and functional over time, enhancing durability and performance.
