TUW-7200 is an alternative to Novec 7200: boiling point 76 °C, dielectric strength 40 kV, surface tension 13.63 mN/m, GWP 55. One fluid serves at the same time as the medium for precision cleaning, hermeticity leak testing and thermostatic baths, and suits electronic production lines with many product variants and small batch sizes.

TUW-5018, TUW-5058, TUW-2704 and TUW-1700 compared: four fluorinated nanocoatings from one family, with clear differences in solids content, film thickness, application method and best-fit use. Includes a selection table and a switching verification checklist for replacing imported conformal coatings.

GPU power and rack power density keep rising, and air cooling is approaching its limit. With a 134 °C boiling point, 1.626 g/mL density, GWP of 1 and strong dielectric properties, TUW-7500 hydrofluoroether gives single-phase immersion cooling a domestically produced alternative.

3M's Novec and Fluorinert lines are being discontinued one after another, and domestic replacement has entered the practical stage. This article provides a master mapping table between the TUW series and 3M, four selection dimensions and five verification actions, helping production lines avoid the trap where the parameters match but the fluid does not work.
