 WinterThaw® DI calcium chloride (CaCl2) based liquid de-icer is specially designed to optimize snow and ice melting. The product contains corrosion inhibiting additives to meet the stringent specifications set for de-icing chemicals by the Pacific Northwest States (PNS) and other state departments of transportation (DOTs). WinterThaw DI (liquid calcium chloride) is used in various de-icing applications to retard cold weather hazards, including snow and ice on roadways. The product meets or exceeds ASTM D98-87 and AASHTO M144-86 standards for de-icing. It exceeds the PNS DOT requirement that de-icers reduce corrosion by at least 70% versus sodium chloride.
Winter Thaw DI also meets other key elements of the PNS specifications, being free of precipitates over a wide temperature range and meeting the specification's strict heavy metal and other impurity levels. |
