Calcium Chloride Dihydrate Powder (CaCl₂·2H₂O) 74-77%

Calcium Chloride Dihydrate Powder (CaCl₂·2H₂O) is a white, free-flowing powder with 74-77% purity. It contains approximately 25% water of crystallization and dissolves readily in water. The fine particle size makes it ideal for rapid brine preparation and precise blending in industrial formulations.

All three forms contain the same 74-77% calcium chloride dihydrate. The powder has the finest particle size, dissolving faster and allowing more precise measurement. Pellets and flakes dissolve more slowly, making them better suited for direct spreading applications like de-icing where controlled release is preferred.

Calcium chloride dihydrate powder is used for preparing liquid calcium chloride brines, dust control on unpaved roads and construction sites, accelerating concrete setting in cold weather, refrigeration brine solutions, and as a raw material for industrial calcium chloride liquid production.

Store in a dry, well-ventilated area in tightly sealed containers. Although the dihydrate form is less hygroscopic than anhydrous calcium chloride, it still absorbs moisture from the air. Prevent exposure to humidity to avoid caking. Under proper storage conditions, shelf life is up to 12 months.

Industrial-grade calcium chloride dihydrate powder is intended for non-food use. For food processing applications such as firming agents in canned vegetables or tofu production, food-grade calcium chloride (E509) should be specified.
