The use of zinc chloride as a flux, sometimes in a mixture with ammonium chloride (see also Zinc ammonium chloride), involves the production of HCl and its subsequent reaction with surface oxides. The action of zinc chloride/ammonium chloride fluxes, for example, in the hot-dip galvanizing process produces H2 gas and ammonia fumes. Relevant to its affinity for these materials, ZnCl2 is used as a fireproofing agent and in fabric refresheners such as Febreze. Vulcanized fibre is made by soaking paper in concentrated zinc chloride. The zinc chloride smoke mixture (HC) used in smoke grenades contains zinc oxide, hexachloroethane and granular aluminium powder, which, when ignited, react to form zinc chloride, carbon and aluminium oxide smoke, an effective smoke screen.
