A white deliquescent, high purity prilled calcium chloride with a typical 94% CaCl2 content. It contains over 20% more calcium chloride than flaked products providing higher heat dissolution, increasing the set acceleration in ready mix applications. It promotes faster melting and a higher penetration rate as a deicer. Hi 94 can be used in oil and gas drilling and as an accelerator for cementitious materials such as grouts and mortars, and ready-mix applications.
