Description
White deliquescent granules or fused pieces. Zinc chloride acts an astringent and antiseptic and has been used to deodorize, disinfect, and embalm specimens. It is used on wood for preservation and fireproofing. With metals, zinc chloride can act as a flux, etchant, cement, and colorant. For textiles, it has been used to mercerize cotton, weight fabrics, mordant dyes, and vulcanize rubber. It is also used in the manufacture of artificial silk, dyes, cold-water glue, and magnesia cements. As a microscopy reagent, zinc chloride is used to separate silk, wool, and plant fibers.
