DOWFLAKE™ XTRA 83-87% CALCIUM CHLORIDE

DOWFLAKE™ XTRA 83-87% CALCIUM CHLORIDE

DOWFLAKE™ Xtra 83-87% Calcium Chloride is a purified inorganic salt produced by removing water from a naturally occurring brine solution. Unlike other processes used to produce calcium chloride, the brine process does not involve reactions with chemicals such as hydrochloric acid or ammonia.

  • Has a higher concentration provides a lower application rate than conventional 77-80% calcium chloride flake
  • Releases heat to melt snow and ice faster, across a wider range of temperatures than other materials

FAQ

How to store DOWFLAKE™ Xtra Calcium Chloride?

Solid calcium chloride is both hygroscopic and deliquescent. This means that the product can absorb moisture from the air, even to the point of converting to liquid brine. For this reason, solid calcium chloride should be protected from excessive exposure to moisture to maintain product quality while in storage. Store in a dry area. Opened packages should be tightly resealed after each use.

To make up solution volumes different from those used as the basis above, simply adjust the “Weight of Product to Dissolve” and the “Water Volume” numbers in the tables by the ratio of the desired solution volume to 100.

How to make calcium chloride solutions From DOWFLAKE™ Xtra?

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 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.
