Daubrite � emitters provide vapor corrosion protection to enclosed metal parts. When the emitter is opened, the Daubert VCI's seek the metal surfaces inside the packaging or enclosure environment and form a protective molecular layer on the surface of the metal. This layer prevents moisture, hydrogen sulfides, salt, dirt, oxygen, and other contaminants from depositing on the metal and causing damaging corrosion.
Each unit prevents metal corrosion, in a 5 cubic feet volume, for up to 2 years. Daubrite-5 VCI emitters come with a convenient ready to use (front) label for recording the date of installation.
