The Solder Tincture WFF is a halogenated flux which can be used for manual, repair and dip soldering. The Solder Tincture WFF is in particular suitable for soldering on ceramic substrates or for braid tinning. The flux has a great temperature stability and a very good activation. The residue behaviour is very good. The flux residues are water-soluble.
