Hostagliss L4

Lubricity improver and corrosion inhibitor for metal working fluids

Edition Date :
August 17, 2022

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.

Benefits
