TUW-7200 Electronic Fluorinated Fluid: Precision Cleaning, Hermeticity Leak Testing, Thermostatic Bath — One Fluid for Three Uses, NO PFAS Domestic Alternative
2026-10-16
A piece of equipment, a circuit board, a test system: each usually needs more than one liquid. Cleaning needs a cleaning agent, leak detection needs a test fluid, and temperature control needs a thermostatic fluid. When a single medium covers all of these needs, procurement, inventory and management costs drop significantly. TUW-7200 is exactly that kind of multi-purpose electronic fluorinated fluid.
1. What Is TUW-7200
TUW-7200 is a thermally stable perfluorinated fluid, benchmarked against 3M Novec 7200. It targets precision cleaning and test-media applications, and it belongs to the PFAS-free (NO PFAS) family of alternatives. It offers excellent chemical inertness and is non-toxic, odourless and non-flammable, with no flash point, low surface tension, good thermal conductivity and no VOC.
2. Main Applications: Precision Cleaning, Airtightness Testing, Thermostatic Fluids and Extraction Solvents
2.1 Precision Cleaning
As an electronic cleaning agent and a precision cleaning agent, TUW-7200 removes grease, flux residues and ionic contaminants from precision parts; as an oil and grease cleaner, it handles the oil and grease involved in equipment maintenance. Low surface tension ensures penetration cleaning of fine structures, and evaporation without residue ensures cleanliness after cleaning.
2.2 Airtightness Test Fluid
Airtightness testing, also called leak detection, needs a medium that does not evaporate, stays chemically stable and leaves the part under test unaffected. The low volatility, chemical inertness and high density of TUW-7200 make it an ideal airtightness test fluid: the medium is not lost during testing and does not react with seals, so results are stable and reliable and the fluid can be reused.
2.3 Thermostatic Fluid and Cooling Medium
TUW-7200 works as a thermostatic fluid and a cooling medium: it holds an accurate temperature in a thermostatic bath and carries heat away from equipment in a cooling loop. Its small viscosity change at low temperature and its good thermal conductivity keep the temperature-control loop responsive and the heat exchange efficient.
2.4 Extraction Solvent and Other Uses
TUW-7200 also serves as an extraction solvent for recovering target components from mixtures; its high insulation also supports use as a test medium in voltage testing. One liquid for many uses significantly lowers chemical procurement and inventory management costs.
3. Environmental Profile and Safety
TUW-7200 belongs to the NO PFAS alternative route: ODP is zero and it does not deplete the ozone layer; GWP is low and cuts the greenhouse contribution sharply compared with conventional PFCs; and the fluid has no flash point and does not burn, so it is safe to use. The product meets RoHS and other environmental requirements and can satisfy the compliance needs of export markets such as Europe, where PFAS controls are tightening.
4. Product Features
The properties of TUW-7200 determine its stable performance in precision cleaning, airtightness testing and temperature control:
4.1 Material Compatibility and Dielectric Performance
Excellent material compatibility, moderate solubility
Good dielectric performance (dielectric constant 7.3 @ 1 kHz, dielectric strength 40 kV)
4.2 Thermal Conductivity, Thermal Stability and Low-Temperature Behaviour
Good thermal conductivity, thermal stability and chemical stability
Small viscosity change at low temperature, pour point down to -138 °C
4.3 Regeneration, Use and Environmental Safety
Drying removes water without leaving water marks
The fluid can be regenerated by distillation and reused
Low environmental burden: colourless, odourless, non-toxic, ODP = 0, low GWP
No flash point, non-flammable, safe to use

6. Choosing Between TUW-7200 and TUW-7300
TUW-7200 and TUW-7300 both belong to the HFE family and differ in application focus: TUW-7200 concentrates on cleaning, airtightness testing and thermostating, while TUW-7300 balances temperature control and cleaning in semiconductor equipment. For test equipment and laboratory work, choose TUW-7200 first; where equipment temperature control also needs cleaning, TUW-7300 fits better.
