Flux HW139

The semi-aqueous, halogen-free No-Clean flux HW139, consisting of a solvent mixture of alcohol and pure, fully demineralised water, meets the current environmental developments. The reduction of the VOC content is particularly advantageous when no VOC-free flux can be used due to application conditions.

Product Advantages

  • good activity and wetting
  • no visible residues
  • high surface insulation resistance
  • no obstruction for ICT


The flux HW139 has been developed primarily for application by spray fluxers. Due to an increased preheating temperature compared to pure alcohol-based fluxes, the water contained can be evaporated well.
