Chemical Profile

Product Overview

Alliance Chemical supplies Calcium Chloride (CaCl₂) , a high-efficiency inorganic salt utilized across industrial, municipal, and commercial sectors. This white crystalline solid is characterized by its extreme hygroscopicity (ability to absorb moisture) and high solubility in water. It is a critical material for exothermic de-icing operations, functioning effectively at lower temperatures than sodium chloride.

Beyond winter maintenance, Calcium Chloride is essential in the construction industry as a concrete accelerator, reducing set times in cold weather. Its hygroscopic properties make it the industry standard for dust control on unpaved roads and as a desiccant in industrial drying systems. This product is manufactured to meet strict specifications, ensuring consistent bulk density and predictable performance in brine formulation and chemical processing.

Key Properties

Chemical Formula: CaCl₂
CAS Number: 10043-52-4
Appearance: White crystalline solid / pellets
Odor: Odorless
Solubility: Highly soluble in water (exothermic reaction)
Specific Gravity: ~2.15 g/mL
Chloride (Cl) Content: Typical 1000 ppm
Hygroscopicity: High (rapidly absorbs atmospheric moisture)

Common Applications

De-icing & Snow Removal: Generates heat upon contact with snow/ice (exothermic) and lowers the freezing point of water significantly, making it superior to rock salt in extreme cold.
Concrete Acceleration: Added to concrete mixes to reduce set time and increase early strength, particularly in low-temperature environments.
Dust Control: Absorbs moisture from the air to keep road surfaces damp, binding aggregate and suppressing fugitive dust on construction sites and unpaved roads.
Desiccant: Used in hydrocarbon drying and moisture removal in industrial packaging and storage environments.
Refrigeration: utilized in brine solutions for refrigeration plants due to its low freezing point depression capabilities.

Safety & Handling

Calcium Chloride is a strong irritant, particularly to the eyes. When mixed with water, it releases significant heat. Personnel should utilize appropriate Personal Protective Equipment (PPE).

PPE: Wear chemical splash goggles, protective gloves, and long sleeves to prevent skin contact.
Storage: Store in a cool, dry place. Containers must be kept tightly sealed; the product will liquefy if exposed to humid air (deliquescent).
Handling: Avoid inhalation of dust. Wash thoroughly after handling.
