Xtra85 Calcium Chloride

High concentration calcium chloride

Xtra85 Calcium Chloride is a purified, concentrated inorganic salt (83-85%). It is designed to melt ice and snow rapidly at temperatures as low as -32 °C (-26 °F). Its high concentration ensures strong performance, while the solid form allows for easier handling, storage, and dosing. Xtra85 Calcium Chloride meets or exceeds ASTM D98 and AASHTO M144 requirements (Type S, Grade 1, Class A).

  • High-purity, calcium chloride for efficient performance
  • Allows lower application rates than conventional 77–80 % flakes
  • Releases heat for faster ice and snow melting across a wide temperature range
  • Absorbs moisture to suppress dust on unpaved surfaces.

Usage

  • Ideal for ice and snow melting on on roads, sidewalks, driveways, and parking lots. It generates heat for faster melting at temperatures as low as -32 °C (-26 °F). It can be mixed with rock salt, sand, or gravel to improve their performance.
  • It can be used as dust suppressant on unpaved surfaces, by absorbing moisture and binding dust particles. 
  • When used in solution, it is effective for tire weighting, brine refrigeration, and as an ingredient in pesticide formulations.

Storage conditions

Solid calcium chloride is hygroscopic and deliquescent, it can absorb moisture from the air, potentially converting to liquid brine. To maintain product quality, store in a dry area and protect from excessive moisture. Opened bags should be tightly resealed after each use. For full safety and handling information, refer to the current Safety Data Sheet (SDS).

Application

Application steps

APPLICATION INSTRUCTIONS

  • Ice melting:

For best results, remove loose snow before spreading. Apply Xtra85 Calcium Chloride at 0.07–0.14 kg/m2 (0.014–0.029 lb/ft2) on asphalt or concrete surfaces designed for freeze–thaw conditions. Avoid excessive application, as it may create slippery surfaces.

  

  • Dust control:

Apply Xtra85 Calcium Chloride at 0.5–0.7 kg/m2 (0.10–0.14 lb/ft2), depending on surface and weather conditions. For best results, apply after light rainfall or light surface watering. Avoid use on paved areas, as the surface may become slippery when wet.

 
  • Tire Ballast: 

Used as liquid ballast, calcium chloride improves traction and extends tire life.

  

  • Solution preparation:

Xtra85 Calcium Chloride releases heat when it is dissolved. Make sure that the dissolving vessel is appropriately constructed for handling hot solutions. Fill the vessel with cool water less than 26 °C (80 °F), then slowly add Xtra85 Calcium Chloride while continuously stirring. Solids kept in motion will dissolve quickly; however, solids that sit motionless on the vessel bottom may form a hard cake that will dissolve more slowly.
