Flux EF270F

The halogen-free activated No-Clean Flux EF270F with its medium activity completes perfectly the EasyFlux series. Using especially matching activators, this flux achieves very good wetting on various surfaces. It can be used for soldering with lead-free and lead containing alloys. The version EF270“F” is equipped with additives, to enable a safe and continuous foaming even on older foam fluxing units. This ensures a uniform flux film on the PCB and therefore a good soldering result.

Product Advantages

  • No-Clean flux
  • Good wetting around and in through holes
  • Nearly no visible residues
  • High electrical safety of the residues
  • Developed for the application with foam fluxing units
  • Resin- and halide free formulation


The flux EF270F is an optimised version of the EF270, which can be used in foam fluxing units. It can be used in spray fluxers, too. Due to the used activator combination, a good wetting can be achieved on most surfaces in the electronics (e.g. OSP, Ni/Au, chem. Sn, HASL). Soldering can be done on nearly all available equipment (with or without nitrogen).
