Lubricity improver for rolling emulsions and cutting & forming fluids

Hostagliss A Terra

Hostagliss A Terra is a complex ester and can be used as lubricity improver in rolling emulsions and cutting & forming fluids. Despite its high viscosity, it can be easily incorporated into concentrates for water based emulsions. The product contributes to emulsion stability and corrosion protection when neutralized with alkanolamines. Furthermore, the product is compliant with medical applications since it is free of animal sources.
  • Good lubricity and anti-wear properties
  • Reduces energy consumption in metal working operations    
  • Easy to emulsify
  • Corrosion inhibiting properties
  • Free of hazardous labeling
  • Broad registration status
  • Free of animal sources
