Dust Control
Why Calcium Chloride?
Calcium chloride is hygroscopic. It constantly draws moisture keeping unpaved roads damp and dust down. Calcium chloride also resists evaporation, providing
long lasting dust control. LIQUIDOW™ also provides base stabilization, structural strength, and freeze thaw protection.
LIQUIDOW™ vs. The Competition
No other material measures up to the performance of LIQUIDOW™ calcium chloride. LIQUIDOW™ provides dust control under conditions where others
lose all effectiveness. Our higher active ingredient allows for the reduction
of application rates resulting in a lower total cost per mile.
