Vertrel® specialty fluids are a family of hydrofluorocarbon-based fluids with zero ozone depletion and low global warming potential. The unique properties of Vertrel® specialty fluids include a low boiling point, low heat of evaporation, excellent solvent retention, low surface tension, low viscosity, non-flammability, chemical and thermal stability, low toxicity, and ease of recovery by distillation. Vertrel® , its azeotropes and blends are compatible with a broad range of materials, metals, plastics and elastomers.

Vertrel® XF is a proprietary hydrofluorocarbon fluid with zero ozone-depletion and a low global warming potential ideally suited for use in vapor degreasing equipment for cleaning, rinsing, and drying. It can replace current hydrochloro- fluorocarbon (HCFC) and perfluorocarbon (PFC) fluids in most applications. Vertrel® XF is HFC 43-10mee or 2,3-dihydrodecaflu- oropentane; empirical formula C5H2F10. It is a clear, colorless liquid

Vertrel® XF is ideally suited for cleaning fine particu- late matter (submicron range) from metal and nonmetal parts. Removal of particle contamination requires a solvent that can minimize the thickness of the laminar boundary layer where particles are bonded to the substrate.

The electronic attraction between particle and surface can be overcome further by increasing the polarity of the fluid through the addition of small amounts of alcohols. Chemours offers a series of proprietary azeotrope and blend compositions which exploit this property
