Hamikleer® 1990 is a bio-resistant synthetic machining and grinding lubricant/coolant for ferrous and non-ferrous metals. It is extremely low foaming, which makes it useful in operations where foam control is essential, such as double disc or plunge grinding, or high speed machining. It provides lubrication needed for light to moderate duty machining operations, such as grinding, turning, drilling, reaming, and tapping. Hamikleer® 1990 is non-staining to non-ferrous metals and has a liquid residual film, which keeps machinery parts moving and provides good lubrication and rust protection to steel. It offers excellent wetting to keep swarf and fines from depositing on machinery, while enabling them to settle out quickly in central sumps. It rapidly rejects contaminants such as most tramp oils. It is highly bacterial resistant, which extends sump life of central and individual systems.
