ZINC CHLORIDE
Ever since the product was released, the main objective was to produce high quality goods at competitive costs. This high quality product can be produced in a water free version (free flowing) or in a solution with a concentration of a minimum of 45 %. The main use of zinc chloride: as an electrolyte is in the production of dry galvanic cells, surface treatment of metals for preparation of melting baths (fluxes), namely in zinc dipping and zinc coating, during chemical syntheses, production of soldering pastes and solutions, tin coating and the manufacture of ion inverters.
Zinc chloride is a white crystalline (also acceptable when having a mild grey tinge which is not detrimental to the use of the product), hydroscopic powder. The substance is odourless, very soluble in water, alcohol, ether, glycerine and acetone.
