OxyChem DOWFLAKE Xtra 20kg 83-87% Calcium Chloride Ice Melter Blend 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 83-87% Calcium Chloride Flakes have 10% more calcium chloride than conventional flake calcium chloride products. They provide more pound-for-pound performance when used for snow and ice control, dust control, road construction and maintenance, concrete acceleration and tire weighting.
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 strength and protection in cold weather.
