Hydrofluoroether (HFE) fluids are specialty fluorinated liquids used in precision cleaning, vapor degreasing, heat transfer, electronics, carrier-fluid applications, and other industrial processes where properties such as non-flammability, low surface tension, dielectric performance, and material compatibility can be important. You may also see them described as HFE solvents, hydrofluoroether solvents, HFE solutions, or simply HFE fluids. […]

PFAS-Free Cleaning Solvents for Vapor Degreasing Applications
PFAS regulations, customer requirements, sustainability initiatives, and supply-chain changes are leading manufacturers to review the chemicals used in their production processes. For companies operating vapor degreasers, this may include evaluating whether a PFAS-free cleaning solvent can meet both current cleaning requirements and longer-term business needs. Choosing a PFAS-free solvent is not simply a matter of […]
BestSolv® Fluids as Coolants for Specialized Machinery and Chiller Systems
Specialized chiller systems are used when equipment, electronics, or industrial processes need precise temperature control. In these systems, the selection of coolant fluids for chillers is crucial, as the coolant is not just a fluid that moves heat. It becomes part of the system’s performance, safety, and reliability. Standard coolants such as water, glycol, or […]
Carrier Fluids for Precision Deposition, Wetting, and Material Transport
Carrier fluids are used in applications where a lubricant, silicone, coating, additive, or active chemistry must be delivered evenly across a surface. Their role is to temporarily carry, thin, or transport another material so it can spread, penetrate, or deposit more effectively before the carrier evaporates. Best Technology offers BestSolv® Engineered Fluids for carrier fluid […]
Surface Finishing Chemicals: Passivation, Electropolishing & Conversion Coatings
What is Post-Wash Surface Finishing? Post-wash surface finishing is the set of chemical or electrochemical processes that take place after a part has been cleaned and before it is placed into service or moved to the next manufacturing step. Cleaning removes oils, soils, and contaminants, but it usually does not create the final surface condition […]
Gross Leak Testing for Hermetic Components and Critical Assemblies
Gross leak testing is a critical step in verifying the integrity of sealed components and assemblies used in high-reliability applications. In aerospace, defense, medical device, automotive, electronics, and other precision manufacturing environments, even a small seal failure can lead to moisture ingress, fluid intrusion, corrosion, contamination, pressure loss, or premature system failure. Using fluorocarbon or […]
Magnesium Cover Gas, Re-Engineered for Today
Why Leading Casters Are Moving to BestSolv® Zulu MAG Magnesium casting requires dependable melt protection. For years, manufacturers had to rely on sulfur hexafluoride (SF₆) and sulfur dioxide (SO₂), despite their significant environmental impact and regulatory pressure. BestSolv® Zulu MAG (FK-5-1-12) is the way forward. Chemically identical to the discontinued 3M™ Novec™ 612, it delivers […]
Oxygen System and Oxygen Gauge Cleaning Solutions
Oxygen system cleaning and oxygen gauge cleaning are often discussed together, but they serve different purposes within oxygen-compatible processes. This page focuses on oxygen system cleaning as it applies to high-pressure oxygen environments, while also addressing oxygen gauge cleaning and oxygen valve cleaning as part of precision cleaning for oxygen delivery systems. The goal is […]
