Zinc Bromide ZnBr Brine
Zinc bromide brine must be used when densities higher than 1.70 kg/I are required. It is supplied in plastic lined drums as a 2.30 kg/I solution. The density is adjusted by mixing this solution with 1.70 kg/I CaBr2/CaCI2 brine.
Zinc bromide brines are toxic and may cause severe burns on the skin. Moreover, ZnBr2 brines are acidic and highly corrosive. Oxygen scavenger, and corrosion inhibitors must be added continuously as the effectiveness of these materials decrease sharply with time.
Zinc bromide brines are always reconditioned for re-use.
