👉 A containment fluid, also known as a sealant or barrier fluid, is a specialized liquid or gel used to prevent the leakage of substances from a container or system. It acts as a protective layer, ensuring that volatile, corrosive, or reactive materials remain confined within their intended boundaries. These fluids are crucial in industries such as chemical processing, pharmaceuticals, and oil and gas, where maintaining the integrity of storage tanks, pipelines, and equipment is paramount. By preventing unwanted interactions between different materials or environments, containment fluids help maintain safety, efficiency, and compliance with regulatory standards.
