Calcium Chloride is a key element in de-icing strategies, which are used by municipalities to maintain tarmac road surfaces in the winter season. These strategies include pre-wetting road salt before applying it to the road, use as an anti-icer before or just after a snow storm begins and treating sand stockpiles to keep them free flowing in cold weather. The ability to liberate heat in an exothermic reaction and to attract moisture creates an effective anti-freeze that helps speed up the melting process and the efficiency of snow/ice removal.

The major advantage of Zirax high purity calcium chloride is that it generates heat as it dissolves, melting more ice faster at lower temperatures. Zirax calcium chloride pellets penetrate ice quicker than medium strength flakes or granules due to their shape and density and fully meet strict environmental requirements applied in this field
