74% Purity Calcium Chloride Hygroscopic Dust Control Chemical for Unpaved Roads
Calcium Chloride For Dust Control On Unpaved Roads And Mining Haul Roads
Calcium Chloride for Dust Control is a hygroscopic salt used to suppress airborne particulate matter on unpaved roads, mining haul roads, and construction sites. The product absorbs moisture from the air and retains it on the surface, binding fine dust particles together.

Applications and Usage
A working solution of 15%–20% calcium chloride is applied by water truck at 0.5–1.5 L/m². Reapplication frequency depends on traffic volume and climate. In mining operations, it is used on haul roads to improve visibility and reduce equipment maintenance. For storage, keep bags closed and elevated from ground moisture.
