Our synthetic coolants are formulated to run virtually clear in machines, provide clean and easy chip flow with none to low mist levels. Using our proprietary ester technology, Stoughcool synthetics have the lubricity to handle tough applications without leaving a sticky or heavy residue. These high performance synthetics reject all tramp oil making it easy for skimmers to remove waste and provide excellent tool life and sump life. Most Stoughcool coolant end users who switch to our synthetics always conclude that they have drastically decreased their coolant usage after making the switch to a Stoughcool synthetic.
