The color changes from yellow (orange) to green as it adsorbs moisture. The color typically begins to change as the moisture content passes 6% by weight and is complete at 14% by weight. A bright green color indicates moisture saturation and that it is time to replace or regenerate the desiccant.
Typical Applications of Yellow Silica Gel:
As primary desiccant or blended with other desiccants in any application where visual control of moisture is required, such as compressed air dryers, gas drying, breathers, for protection of non-consumable packed goods, drying and storage of flowers and seeds, etc. Due to the addition of the moisture indicator, sSORB yellow indicating silica gel should not be used in contact with products intended for consumption such as food or pharmaceuticals.
