Anhydrous Calcium Chloride (as drying agent)
Anhydrous Calcium Chloride Mini-Pellets are commonly used to formulate high density, solids-free drilling fluids for the oil and gas industry. The product is also used in concrete acceleration and dust control applications.
Anhydrous Calcium Chloride is a purified inorganic salt produced by removing water from a naturally occurring brine solution. Calcium chloride is used as desiccants, de-icing agents, food additives and plastics additives.

Solid calcium chloride is both hygroscopic and deliquescent. This means that the product can absorb moisture from the air, even to the point of converting to liquid brine. For this reason, solid calcium hloride should be protected from excessive exposure to moisture to maintain product quality while in storage. Store in a dry area. Opened packages should be tightly resealed after each use.
CaCl2 is mostly used as a desiccant, such as for the drying of nitrogen, oxygen, hydrogen, hydrogen chloride, sulfur dioxide and other gases. Used as a dehydrating agent in the production of alcohols, esters, ethers and acrylic resins. Calcium chloride aqueous solution is an important refrigerant for refrigerators and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze. It is used as antifogging agent in port, road dust collector and fabric fire retardant. Used as protective agent and refining agent in aluminum-magnesium metallurgy. It is a precipitant for the production of lake pigments. Used for deinking of waste paper processing. It is the raw material for the production of calcium salts. In the food industry, it is used as a chelating agent and a coagulant.
