Silica gel is a sturdy, porous, reusable desiccant that can be used to shield the valuables from moisture-related harm by lowering humidity levels to below 30% (within enclosed spaces) and avoiding fungus, mildew, and rust development. Unlike certain other desiccants, silica gel does not absorb moisture and does not get damp or balloon in size. It's all non-corrosive, odourless, chemically inert, and produces little waste. In addition, before requiring reactivation, our silica gel will absorb up to 1/3 of its weight in moisture.
This form of silica gel includes an orange signalling dye that can eventually turn dark green to show when the silica gel is complete and no longer able to retain moisture until reactivated – there are no limitations to how many times it can be reactivated.
Precautions: Inhalation of dust produced by orange silica gel should be avoided at all costs. All kinds of silica gel should be kept out of sight of children and should not be consumed (may pose as a choking hazard). Since this silica gel is not FDA approved, it is not recommended for use as food.
Reactivation instructions: Reactivate the orange silica gel by doing the following: Heat the silica gel beads in an oven-safe tray for 3-4 hours at 105° to 115°C. Allow the beads to cool before storing them in an airtight container until needed.
