Ice Fighter Plus® is the only unique premium snow and ice melter that reduces freeze/thaw damage to concrete. 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. Ice Fighter Plus® reduces freeze/thaw damage to concrete. 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.
