Calcium chloride for de-icing – why does it work better than NaCl?

Temperature limit – key difference

Road salt (NaCl) loses its effectiveness below –7°C. Calcium chloride (CaCl₂) works up to –52°C, which makes it irreplaceable in severe frosts.

Exothermic reaction

CaCl₂ releases heat upon contact with ice, accelerating its melting. NaCl absorbs heat from the surroundings - the opposite effect.

Dosage comparison

• NaCl: 15–30 g/m²
• CaCl₂: 10–20 g/m² - more effective at lower doses

When is it worth using CaCl₂?

• Temperatures below -7°C
• Preventive actions against rainfall
• Airports, highways, mountain areas
