Stannol WF300F and WF300S are low residue, halide-free fluxes, which meet the most demanding legislation on volatile organic compound (VOC) emissions.

The No-Clean Flux WF300F and WF300S is water-based and suitable for use everywhere  it is wished to dispense with organic solvents. Due to an increased solid content, it is possible to reduce the volume to be applied so that the water as solvent can also be well evaporated in the preheating of the wave soldering machine.

  • The flux WF300F has been specially developed for use in a wave soldering system with foam fluxer.
  • The flux WF300S has been specially developed for use in a wave soldering system with spray fluxer.
Use with and without a nitrogen atmosphere is possible here. Further optimisation for the solder bead reduction has also been performed.
