ABSTRACT:
The thermal resistance of a zinc chloride/ammonium chloride galvanizing preflux is improved by incorporating therein boric acid, other alkali metal chlorides and an aliphatic amino derivative. An improved zinc chloride/ammonium chloride galvanizing, top-flux includes a deoxidizer such as graphite or charcoal, other alkali metal chlorides and a foaming agent. Both compositions, the preflux and the top-flux, can be used to advantage in galvanizing steel with low lead or no lead zinc.
