Calcium Chloride (30% in Water) (CaCl2, CAS 10043-52-4) solution is a clear, colorless to slightly cloudy brine with a specific gravity of about 1.30 that stays liquid well below 0°F. It is used for road deicing and anti-icing, dust control, road base stabilization, concrete set acceleration, refrigeration brines, and oilfield completion fluids. Liquid calcium chloride is corrosive to steel, so poly storage tanks are widely used. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
