Precision Cleaning & Heat-Transfer Fluids

What is Hydrofluoroether (HFE) Solvent Cleaning?

Hydrofluoroethers (HFE) represent a category of organic solvents. They were initially developed to replace CFCs, HFCs, HCFCs, and PFCs with non-ozone-depleting substances. Perfluorocarbons (PFCs) and chlorofluorocarbons (CFCs), which are used for crucial applications like the fabrication of medical devices and microelectronics, are generally considered as safer and more ecologically friendly alternatives to HFEs.

Fluorosolvents, such HFE-347, can penetrate the surface of the contaminant while being kind to the surface of the substrate thanks to their low surface tension. Fluorinated cleaning solutions can be used to thoroughly clean a variety of substrates, including metals, plastics, polyurethanes, and fluoroelastomers.


What Industries Are Fluorinated Solvents Used In?

  • Medical device manufacturing
  • Semiconductor chip & wafer processing
  • Aerospace
  • Automotive
  • Industrial Processes


  • Heat Transfer
  • Two-Phase Immersion Cooling Fluid
  • Cleaning– oils, greases, fluxes, waxes, particulates, lubricants, fluoropolymers
  • Carrier solvent for coating
  • CFC, HCFC, HFC, and PFC replacement

Benefits of Choosing An HFE-Based Solvent Cleaner?

Solvents are used for extremely vital items, such as medical equipment and instruments, where a strict degree of sanitation is required before assembly or shipping. Fluorinated solutions penetrate and dissolve the contamination without harming the surface of the thing being cleaned, whether the object is composed of metal, plastic, polyurethanes, or another material thanks to their low surface tension feature. Different solvents, or solvent blends, can be chosen to remove pollutants of any kind, depending on the type of contamination.

Fluorinated solvents also offer the following advantages:

– A faster rate of evaporation than aqueous solutions

– Less energy is needed to clean;

– Next generation fluorinated solvents have low global warming potential (low GWP) and ozone depletion potential (low ODP).


HFE-347 as Cleaning Solvent

Vapor degreasing is the process of using chemical vapor to remove greases, oils, and other contaminants from the surface of various materials in various industries. This cleaning process consists of bringing the solvent to its boiling point thus creating vapor, bringing the solvent to a gaseous state. The material is then submerged in the solvent vapor, creating condensation on the surface of the material which is

A vapor degreaser system condenses the cleaning solvent into vapor which attach to the material or object that is being cleaned. As the vapor evaporates, it is removing the unwanted contaminants from the surface.

Vapor degreasing is a highly effective method for cleaning and preparing materials to continue their course down the production line. Vapor degreasing should assist in the following areas:

  • Faster cleaning than other precision cleaning methods
  • Improves manufacturing processes for the parts being cleaned, resulting in a more effective production line
  • Prepares the materials or parts for finishing processes such as welding and/or painting


HFE-347 for Heat-Transfer Applications

HFE-347 is an engineered fluid that can be used in heat-transfer applications such as immersion cooling or thermal management of electronic components. Due to properties such as non-flammability and non-corrosivity, solvents can be used in a wide variety of electronic materials such as metals and plastics.

All systems require different conditions which require different heat-transfer solvents. When looking for a good heat transfer fluid, one can consider these characteristics for the heat

  • Ranging boiling temperatures
  • Pour point and viscosity
  • Thermal and heat transfer properties
  • Material compatibility
  • Flash point and flammability
  • Toxicity of the substance


Why Are Other Solvents Being Phased Out? CFC, HCFC, HFC

Chlorofluorocarbons were previously the preferred cleaning solvent for many industries before they were classified as harmful to the environment due to their high ozone depletion potential (ODP). Ozone-depleting solvents are forbidden by the Montreal Protocol, forcing these businesses to find, test, and use new substitutes. Popular alternatives due to their environmentally sustainable chemical properties are fluorinated solvents or aqueous solvents, which are determined and managed by the EPA’s SNAP program- the authority governing the use of ozone-depleting substances to thwart damage to our climate. Many of the largest game players in the


3M™ Announces Phaseout of PFAS 

By the end of 2025, 3M plans on discontinuing the manufacturing of their per- and polyfluoroalkyl substances (PFAS) across its entire product portfolio. This comes about due to growing concerns and lack of research regarding the affects of these substances in our environment. For industrial cleaning processes such as solvent degreasing of precision parts or thermal management of electronics, 3M’s Novec cleaning solvents will no longer be utilized.

3M™ Novec™ Products That Are Affected By The Phaseout:

  • 3M™ Novec™ 7100 Engineered Fluid
  • 3M™ Novec™ 7200 Engineered Fluid
  • 3M™ Novec™ 7300 Engineered Fluid
  • 3M™ Novec™ 7500 Engineered Fluid
  • 3M™ Novec™ 71DA Engineered Fluid
  • 3M™ Novec™ 72DA Engineered Fluid
  • 3M™ Novec™ 71DE Engineered Fluid
  • 3M™ Novec™ 72DE Engineered Fluid
  • 3M™ Novec™ 73DE Engineered Fluid
  • 3M™ Novec™ 71IPA Engineered Fluid
