Calcium Chloride (Saturated) is a concentrated CaCl2 brine near its solubility limit, around 40% to 45% depending on temperature, with a specific gravity of about 1.43. It is heavier than standard 30% liquid calcium chloride. Saturated brine is used as a dense oilfield completion and workover fluid, for ballast, in industrial drying and in high-strength deicing blends. Crystals can form as the temperature drops, so tanks may need heating or periodic mixing. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
