Boost with Calcium Chloride is an anti-icing/de-icing material additive produced from natural renewable resources. According to manufacturer, offers lower freeze-point protection, higher viscosity and superior corrosion protection compared to other ice-control products on the market. Boost is designed to lower application rates and slow the dilution rate for increased operational efficiencies. Lower application rates can calculate to significant savings per mile. Requires no filtering. Boost is a free-flowing material that will not plug spray nozzles. Stays in suspension while stored over long periods of time and in colder climates. Prevents freezing or “chunking.” Readily available in bulk quantities, Boost can be used in bridge systems without plugging smaller nozzles. Ideal for pre-wetting salt and sand.
