  • Stable
  • Non-flammable
  • Extremely low Global Warming Potential (GWP)
  • Zero Ozone Depleetion Potential (ODP)
  • Not a HAP
  • Fast Drying
  • Low surface tension, low viscocity, high liquid density
  • Excellent permeability
  • Azeotrope-like blend
  • Thermally and hydrolytically stable
  • Recoverable by simple distillation
  • Flash Point (Open/Closed cup): None

Tergo HDF cleans a broad range of soils commonly found in the aerospace, automotive, medical, oil exploration and industrail sectors using either open-top or vacuum vapor degreasers.

This solvent is an azeotrope-like blend that can stand up against thermal breakdown and continue to clean parts to the highest cleanliness standards. 

Tergo HDF is compatible with a broad range of substrates, while solvating soils such as heavy hydrocarbons, greases, caramelized residues, waxes and silicone oils.

Tergo HDF is a non-flammable solvent that does not contain Ozone Depleting Substances and has one of the lowest GWP values in the market, thus offering the benefits of low surface tension, low viscosity cleaning while minimizing its environmental footprint.

While Tergo HDF is for efficient use in a vapor degreaser, it is also ideally suited as a line flush fluid, or for solvent extraction applications.
