De-icing Salt

• De-icing salt is basically natural Sea Salt with Purity of NaCl ranging from 95 to 99.50% available in White Crystalline form with grain size 0.5 to 10mm.
• To improve melt and grip of ice, salt has to be coarser than normal grain. Although, we can provide both: finely grained and coarse grain.

•           Why salt is used in de-icing?
•   -  Salt melts ice based on the process called “Freezing point depression”. It means salt lowers the freezing point of water.
•   -  Salt makes it more difficult for water to freeze. In ideal conditions, 15 % salt solution freezes at 20°F (-6.6 °C), and a 25 % solution freezes ​at 2°F (-16.6 °C).
•   -  Salt is the most effective option because of applying easily, low cost, etc.
