Introduction Name:Calcium Chloride CAS No:10043-52-4 Formula:CaCl2 Calcium Chloride For Snow and Ice Control,it is an inorganic salt,its CAS number is 10034-52-4 and formula is CaCl2.Calcium chloride has long been a staple and the backbone of premium high performance deicers. Application 1.It is hygroscopic, strongly attracting moisture from its surroundings. 2.Solid calcium chloride is deliquescent, meaning it can absorb enough moisture to convert to liquid brine. 3.When dissolved in water, solid calcium chloride releases heat in an exothermic reaction. These three special properties of calcium chloride are highly beneficial to quickly melt ice on sidewalks and steps.
