Calcium Chloride Flake 77% Road Grade 25kg bag
Calcium chloride offers an extremely low de-icing temperature of around -32°C. Like sodium chloride, it is a hygroscopic material that attracts moisture, quickly starting the de-icing with the formation of brine. Unlike sodium chloride, calcium chloride is exothermic, releasing heat as it dissolves in water. It is a particularly effective de-icer at colder temperatures which serves to heat up the surrounding area upon application, kick-starting the melting process.
