Liquid fluxes
The use of zinc ammonium chloride in hot dip galvanizing is extremely important to protect the piece from oxidation and to
prepare it for the immersion in the zinc bath.
SANIMET spa produces double and triple flux salt, especially studied for the maximum efficiency in hot dip galvanizing.
The availability in a liquid, ready-to-use form makes allows a very simple, fast and cost saving use, thanks to the possibility to dose exactly the needed quantity.
