The investigations and research were conducted at an independent civil engineering lab. Ice Fighter Plus® is a two component system consisting of the ice melter and Propolyice patented inhibitor. During the manufacturing process, the Propolyice's anti-caking agents and chemical additives are mixed with and coated onto the ice melter (sodium chloride crystals) in such a manner as to produce a uniformly coated product. Melted water combines with Propolyice to form a polymer barrier that reduces the amount of water entering into the pores of the concrete. Entrapped water now has room to expand as freezing occurs.
