SeaDry offers effective long-term protection against moisture, whether for container transports by ship, goods train and truck or also when using containers as (temporary) storage. To ensure the high absorption capacity and reliable moisture absorption of all SeaDry variants, we use optimally coordinated ingredients. In particular, the salt (calcium chloride) must be of high quality and is used in the form of powder whose grain size corresponds to that of the starch also used. This allows the two substances to mix evenly in the desiccant bags. The salt then attracts the moisture from the air in the container, which is safely bound into gel by the starch and is not liquid at any time. SeaDry is thus superior to other container desiccants, which contain cheaper salt in the form of significantly coarser prills (instead of powder).
