Low frictional properties reduce chatter and stick-slip of slides and ways and lead to improved surface finish and dimensional accuracy of workpieces . Excellent demulsibility provides ready separation from soluble cutting fluids and leads to prolonged coolant life and reduced cost of replacement and disposal. Superior metal wetting properties and adhesiveness resist wash-off from critical surfaces and protect from attack of high pH coolants. Good filterability provides easy circulation through filters and reduces stick-slip, chatter and wear. Excellent anti-wear performance provides high levels of protection for gears, bearings and slides. Effective rust and corrosion inhibitors provide enhanced protection of machine tool slides even in presence of aqueous cutting fluids. Good thermal and oxidative stability keeps sliding surfaces clean and resists oil degradation thereby increasing its service life.
