These are unique heavy-duty, synthetic coolant concentrates containing lubricity agents, anticorrosion
additives and other components to satisfy the demands of today’s high-performance machining operations. When diluted with water in the proper concentrations, these premium products function as heavy-duty cutting fluids. Containing no oil, these fluids show distinct advantages over the more conventional ‘‘soluble’’ or ‘‘emulsifiable’’ cutting oils commonly used in industry, particularly in the areas of ease of mixing and cleanup, improved solution stability, freedom from odor and rancidity, heat transfer, and work face visibility.

CITGO Quench oils are designed especially for the heat treatment of steel in a wide variety of quenching operations.
