The Solder Tincture WFF is a halogenated flux which can be used for manual, repair, and dip soldering. The Solder Tincture is suitable particularly for soldering on ceramic substrates or for braid tinning. The flux has a great temperature stability and a very good activation. The residue behavior is as well very good. The flux residues are water-soluble.
Application (recommended): Manual- and repair soldering, dip soldering

Customer added value:

  • Wide range of applications
  • Soldering on ceramic substrates
  • Braid tinning
  • Very good soldering properties (capillarity, wetting)
  • Broad process window (very high thermal stability, good activity over a long interval)
  • Very good residue behaviour (water-soluble)
