Lubricity improver and corrosion inhibitor for metal working fluids
Hostagliss L4
Edition Date :
August 16, 2023
Hostagliss L4 is a complex ester and used as lubricity improver and water-dispersable corrosion inhibitor for milky, semisynthetic and neat oil metalworking fluids. Furthermore it is used as synthetic base fluid for rolling emulsions. Hostagliss L4 is also listed on the “Lubricant Substance Classification list (LuSC). Thus suitable for lubricants with European Ecolabel certification.
