    Calcium Chloride Dihydrate CAS 10035-04-8

    Calcium Chloride Dihydrate CAS 10035-04-8 is a hygroscopic inorganic salt chemically defined as calcium dichloride dihydrate , functioning primarily as a rapid setting accelerator in concrete formulations and a density-modifying agent in oil drilling brines. Also known as Calcium chloride 2-hydrate or Hydrophilite, this flake or granular material is utilized to facilitate low-temperature curing in cementitious systems and acts as a desiccant in industrial drying processes. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

    Primary Applications

    1. Oil & Gas Industry (Oilfield Grade)

    In drilling, our Dihydrate Calcium Chloride is used to increase the density of clear-water brines and to provide inhibitive properties to drilling muds, preventing the swelling of reactive clays in the wellbore.

    2. Road Maintenance & De-icing

    It is one of the most effective de-icers available. It works at temperatures as low as -25°C, significantly lower than traditional rock salt. It is also used as a dust suppressant on unpaved roads by absorbing moisture from the air to keep the surface damp.

    3. Food Processing (E509)

    • Cheese Making: Restores calcium balance to heat-treated milk.
    • Canning: Acts as a firming agent to keep vegetables (like pickles and peppers) crunchy.
    • Brewing: Adjusts mineral content in water to influence the beer’s flavor and yeast activity.

    4. Construction (Accelerator)

    Added to concrete mixes to speed up the initial setting time, especially in cold weather environments, allowing for faster project completion.

    Storage & Handling

    The “Sponge” Effect: Calcium Chloride is highly hygroscopic. This means it will actively “pull” moisture out of the air.

    • Storage: Must be stored in a dry, cool warehouse. Keep bags tightly sealed.
    • Caking Prevention: Even if the chemical purity remains unchanged, caking can make it difficult to use. Always store on pallets and avoid stacking more than 20 bags high for long periods.
    • Shelf Life: 24 months, provided the moisture-proof seal is not compromised.

    Safety Precautions

    • Exothermic Reaction: When dissolving Dihydrate Calcium Chloride in water, it releases heat. Always add the chemical to water slowly while stirring. Never add water to a pile of Calcium Chloride.
    • Skin & Eye Protection: It is a desiccant. Direct contact will dry out skin and irritate eyes. Wear safety goggles and gloves.
    • First Aid: In case of contact with eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical advice.

    Why Source From Us?

    We understand that for an importer, the color and the pH stability of the brine are just as important as the CaCl2 percentage. Our production lines are equipped with optical sorters to ensure our flakes remain pure white, and our laboratory tests every batch for heavy metal compliance.

    FAQ - Technical & Supply Chain

    • Q:

      How is Calcium Chloride Dihydrate (CAS 10035-04-8) chemically distinguished from the anhydrous form?

      A: Calcium Chloride Dihydrate is identified by CAS 10035-04-8 and contains two water molecules per crystal lattice (𝐶𝑎𝐶𝑙2), resulting in a typical assay of 74-77%. This distinguishes it from Anhydrous Calcium Chloride (CAS 10043-52-4), which has a higher assay (>94%) and significantly higher heat of solution, making the dihydrate safer and more controlled for specific exothermic applications.
    • Q:

      What is the primary industrial application of Calcium Chloride Dihydrate in construction?

      A: In the construction and cement industry, this material is intended for use as a setting accelerator. It is added to concrete mixes to reduce setting time and increase early strength development, particularly in cold weather environments where standard curing rates are too slow.
