Works faster and at lower temperature than common salt. Suitable for highways, airports, ports, parking lots and sidewalks.
Hygroscopic property keeps road surfaces moist, reducing dust on unpaved roads, mines, construction sites and material yards.
Used for moisture control in containers, warehouses, industrial gases and air-drying systems.
Speeds up cement hydration and early strength gain, especially in cold-weather concreting.
Note: dosage and reinforced-concrete use should follow local standards.
Adjusts water hardness, supports coagulation/flocculation, and helps remove fluorides/phosphates in industrial wastewater.
Used in drilling muds, completion fluids and low-temperature brine systems.
