Calcium Chloride is the most aggressive absorber. As the salt absorbs moisture from the air a saline solution – a brine – is formed. This brine needs to be handled with care. It is strongly corrosive on metals. If left exposed to the air, the brine will under some circumstances give up the moisture it as absorbed in a way that can cause great damage, in some cases even leaving a briny pool.
Super Dry Desiccant extracts water vapor from the air, thus preventing the humidity inside the container reaching dew point and condensing. Once water vapor has been absorbed, the desiccant turns to gel and the water is retained by binding agents.
Amylopectin works for hardening of the absorbed moisture to form gel and retention within the Dry Sac.
