Immersion Leak Testing Additives

By lowering the surface tension and increasing the wetting ability of water, a leak in a pressurized immersed vessel will generate a steady stream of tiny bubbles instead of an occasional larger bubble as with untreated water. Small leaks will produce bubble indications that are impossible with normal water. The CIM Immersit series will not foam, will not support bacteria growth and are formulated to prevent corrosion. Although their use is recommended with deionized  or distilled water, they are chelated to be compatible with mildly hard water. Immersit additives are biodegradable. They meet the requirements of ASTM E515 Sec 8 on Immersion Leak Testing.
