Using Water Guard Moisture Control (WGMC) Desiccant Sachets

When you open the individual packages containing the WGMC Desiccant Sachets, the granular material inside the sachet will be activated. When installed in an enclosure or case, WGMC Desiccant Sachets absorb moisture from the atmosphere and stabilizes the ambient relative humidity to a near constant level.
