DOWFLAKE Xtra 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. The National Organic Standards Board noted this distinction when it classified the brine process as “non-synthetic.” DOWFLAKE™ Xtra meets or exceeds ASTM D98 and AASHTO M144 requirements for calcium chloride purity. ASTM classication for DOWFLAKE™ Xtra is Type S, Grade 1, Class A.
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.
DOWFLAKE™ Xtra releases heat to melt snow and ice faster and across a wider range of temperatures than other materials. 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.
Adding it to concrete results in reduced time for initial and final set, increased early strengh 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 is pesticide formulations.
