DOWFLAKE™ Xtra 83-87% Calcium Chloride | 50 lb. Bag(s)

DOWFLAKE™ Xtra 83-87% Calcium Chloride possesses distinctive properties that make it the ideal choice for ice melting, dust control, concrete acceleration, and many other applications. Its higher concentration provides a lower application rate than conventional 77-80% calcium chloride flake.

CALCIUM HARDNESS INCREASER.
Calcium chloride is used to increase calcium levels in swimming pool water. Proper calcium levels (200-400ppm) protect the swimming pool structure itself by preventing the water from pulling calcium out of the concrete shell and plaster finish. Water will always try to naturally balance itself so low calcium levels can cause cracking in the pool wall and plaster deterioration over time. 

ICE MELT.
DOWFLAKE™ Xtra releases heat to melt snow and ice faster and across a wider range of temperatures than other materials.

DUST CONTROL.
Mix it with rock salt, sand, and gravel to improve their performance. It reduces dust on unpaved surfaces by absorbing moisture from its surroundings, keeping the surface damp and binding dust particles to the gravel.

CONCRETE ACCELORATOR.
Adding it to concrete results in reduced time for initial and final set, and increased early strength and protection in cold weather.

When put into solution, DOWFLAKE™ Xtra is effective in many other applications, including tire weighting brine refrigeration, and as an inert ingredient in pesticide formulations. (See tables on reverse.)

DOWFLAKE™ Xtra meets or exceeds ASTM D98 and AASHTO M144 requirements for calcium chloride purity. ASTM classification for DOWFLAKE™ Xtra is Type S, Grade 1, Class A.
